Why the temperature did not change although heat was added to it when the potential energy of the molecules increases?
Precisely because the heat energy that was added was used up elsewhere. Temperature is a kind of kinetic energy; a change of phase (like, from solid to liquid) is a kind of potential energy.

Does the molecules in a solid have motion or energy?
As temperature of a solid is increased, molecular motion increases.Since, temperature of a solid is directly proportional to average vibrational kinetic energy of molecules of a solid, therefore, energy of a solid increases with an increase in temperature. So, it demonstrates that molecular motion is directly proportional to energy i.e. the higher the energy of solid, the higher is the molecular motion.
Which property will eventually be the same for two objects after heat is transferred between them?
A wrong Idea:Often the concepts of heat and temperature are thought to be the same, but they are not.Perhaps the reason the two are usually and incorrectly thought to be the same is because as human beings on Earth everyday experience leads us to notice that when you heat something up, say like putting a pot of water on the stove, then the temperature of that something goes up. More heat, more temperature - they must be the same, right? Turns out, though, this is not true.Initial Definitions:Temperature is a number that is related to the average kinetic energy of the molecules of a substance. If temperature is measured in Kelvin degrees, then this number is directly proportional to the average kinetic energy of the molecules.Heat is a measurement of the total energy in a substance. That total energy is made up of not only of the kinetic energies of the molecules of the substance, but total energy is also made up of the potential energies of the molecules.More abut temperature:So, temperature is not energy. It is, though, a number that relates to one type of energy possessed by the molecules of a substance. Temperature directly relates to the kinetic energy of the molecules. The molecules have another type of energy besides kinetic, however; they have potential energy, also. Temperature readings do not tell you anything directly about this potential energy.Temperature can be measured in a variety of units. If you measure it in degrees Kelvin, then the temperature value is directly proportional to the average kinetic energy of the molecules in the substance. Notice we did not say that temperature is the kinetic energy. We said it is a number, if in degrees Kelvin, is proportional to the average kinetic energies of the molecules; that is, if you double the Kelvin temperature of a substance, you double the average kinetic energy of its molecules.More About Heat:Heat is energy.Heat is the total amount of energy possessed by the molecules in a piece of matter. This energy is both kinetic energy and potential energy.When heat, (i. e., energy), goes into a substance one of two things can happen:1. The substance can experience a raise in temperature. That is, the heat can be used to speed up the molecules of the substance. Since Kelvin temperature is directly proportional to the average kinetic energy of molecules in a substance, an factor increase in temperature causes an equal factor increase in the average kinetic energy of the molecules. And if the kinetic energy of the molecules increase, the speed of the molecules will increase, although these increases are not directly proportional. The kinetic energy of a body is proportional to the square of the speed of the body. 2. The substance can change state. For example, if the substance is ice, it can melt into water. Perhaps surprisingly, this change does not cause a raise in temperature. The moment before melting the average kinetic energy of the ice molecules is the same as the average kinetic energy of the water molecules a moment after melting. Although heat is absorbed by this change of state, the absorbed energy is not used to speed up the molecules. The energy is used to change the bonding between the molecules. Changing the manner in which the molecules bond to one another constitutes a change in potential energy. Heat comes in and there is an increase in the potential energy of the molecules. Their kinetic energy remains unchanged.So, when heat comes into a substance, energy comes into a substance. That energy can be used to increase the kinetic energy of the molecules, which would cause an increase in temperature. Or that heat could be used to increase the potential energy of the molecules causing a change in state that is not accompanied by an increase in temperature.my source (i give all credit to the website below for they are the ones who had this fancy answer): i hope that this was of some help to youhttp://id.mind.net/~zona/mstm/physics/mechanics/energy/heatAndTemperature/heatAndTemperature.html
Does molecular motion stop when diffusion stops?
No, molecular motion does not stop when diffusion stops. Molecular motion refers to the movement of molecules within a substance, which continues even when there is no net movement of molecules from one region to another (diffusion).
Can gases and liquids carry heat by conduction?
Yes, gases and liquids can carry heat by conduction, although they are generally considered to be poor conductors compared to solids. In gases and liquids, heat is transferred through collisions between molecules and the flow of energy from higher temperature regions to lower temperature regions.
Does a gas have mass and volume and state?
Yes, a gas has mass because its molecules have mass. A gas also has volume, although this volume can change based on the conditions it is in. A gas can exist in different states (solid, liquid, gas) depending on its temperature and pressure.
How does temperature effect vapour pressure of a liquid?
as the temperature increase the liquid becomes less condensed and the pressure decreases. as its molecule lossen they move faster, the liquid will turn into a gas. if the temperature decreases then it will do the opposite. it would slow down the molecules, and increase the pressure, making a solid.
Why does increasing the temperature of a reaction increase its rate?
It provides energy to overcome the activation energy.
Why does solubility of solids and gases change with temperature?
The solubility of solids generally gets higher as the temperature gets higher. (apart from with calcium hydroxide- limewater). The opposite is true for gases- their solubility decreases as the temperature increases.
What happens to the solubility of a solid in water as the temperature increases?
In general, the solubility of most solids in water increases as the temperature increases. This is because higher temperatures provide more energy for the solvent molecules to interact with and break down the solid particles, allowing more of the solid to dissolve in the water. However, there are exceptions where the solubility of certain solids may decrease with increasing temperature, depending on the specific substances involved.
What are the changes when you go through the atmosphere?
Although there are many gas molecules that surround you on Earth,there are fewer and fewer gas molecules in the air as you move away from Earth's surface. so, as altitude increases, air pressure decreases.
Does the molecules in a solid have motion or energy?
As temperature of a solid is increased, molecular motion increases.Since, temperature of a solid is directly proportional to average vibrational kinetic energy of molecules of a solid, therefore, energy of a solid increases with an increase in temperature. So, it demonstrates that molecular motion is directly proportional to energy i.e. the higher the energy of solid, the higher is the molecular motion.
How temperature affect the reaction rate?
Higher temperature increases rateFor the very large majority of chemical reactions, increasing the temperature increases the rate of the reaction. This is because nearly all chemical reactions have some activation barrier which must be surmounted before the reaction can proceed, and the added temperature helps to get over this barrier. There are however some processes which do not speed up with increased temperature, although there much fewer. The freezing of water is one obvious example.AnswerHeating chemical substances can make the molecules separate and move around faster. This can increase the speed with which they mix with surrounding molecules from other chemical substances, thus speeding up a reaction. This is not always the case, some chemicals will only react when cold...While it is true that hotter molecules move faster, it is not the improved mixing that makes reactions occur faster -- otherwise you could just stir more effectively and not have to heat! Heating gives the molecules more energy to surmount the activation energy barrier of the reaction. The more energy the reactants have, the more of them can surmount this barrier, which is required for the reaction to occur. The reason some reactions don't go faster when heated is because they do be activationless or the barrier may be so high that other methods are necessary to give the reactant sufficient energy to surmount the barrier.See the Related Question below for more information.
How is privacy affected by computer technology?
Although computer technology makes data easier to compile, combine, and circulate, it dramatically increases potential violations of personal privacy and security.
How is the temperature of a substance related to attraction between molecules and its states?
Gases have the most kinetic energy and the least attraction exists between its molecules. Liquids have the middle amount of kinetic energy and middle attraction. Solids have the least kinetic energy and most attraction exists between its particles. The answer above isn't totally accurate, although it is mostly right. However, the attraction between molecules DOES NOT CHANGE WITH TEMPERATURE. What changes is how much energy the atoms/molecules have to overcome that attraction. The higher the temperature, the more energy the molecules have, and therefore the less the attractive force between will actually pull them together. As an example, consider a space rocket. The force of gravity on the rocket is constant. However, when the rocket is launched, the rocket's engines overcome the attractive force of gravity (by accelerating in the opposite direction) and therefore the rocket takes off. The attractive force doesn't change -- but the rocket's engines are more powerful than that attraction. In the same way, the increased temperature doesn't change the attraction, but it allows the molecules to overcome it. Other example. Image you are rolling down a hill on a bicycle. In the middle of the downhill, there is a rise. Because you have speed from going downhill, this slight uphill section doesn't stop you. However, the slight uphill is still there! It just doesn't stop you because you are already going fast. But it still affects you.

Why does sugar raise boiling point?
Sugar increases the boiling waters temperature because it is an impurity. Impurities are dissolving molecules. Another example of an impurity is salt, although salt has a much greater affect on boiling water than sugar does. Impurities will increase water's boiling point because they are able to dilute the concentration/ solution of the water. In other words: the amount of water molecules will decrease and so will the amount of molecules that are able to vaporize at the specific temperature. This causes the need for a higher temperature in order to gain the same amount of vapor pressure, thus raising the boiling point.
If you increase the temperature of an object does it affect the volume?
Yes, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume.
