How are temperature and heat related?
Assuming that you mean heat to be the internal energy of a system or object. Than temperature is a method to measure this. The second law of thermodynamics clearly shows the relation: dQ = TdS where Q is the change of heat in a system T is the temperature S is the change of entropy, which can never decrease per definition
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
What is the relation between heat and temperature?
The difference between heat and temperature is that heat is the amount of energy given off by a piece of matter, and Specific Heat indicates the amount of heat necessary to change 1g of something by 1 degree. Temperature measures change in heat.
What best describes the relationship between heat and temperature heat and temperature are the same thing heat changes temperature heat is a measure of temperature or temperature measures?
Heat and temperature are related but not the same thing. Temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy between objects due to a temperature difference. Heat can change the temperature of an object by transferring energy to it.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
During the process of melting and boiling, the heat energy supplied is being used to break the intermolecular forces holding the substance together. This energy is known as latent heat and does not result in a temperature increase because it is being used to change the state of the substance rather than raise its temperature. Once all the substance has melted or boiled, any additional heat energy supplied will then raise the temperature.
What happens to the heat energy which is supplied to the solid once it has started melting?
During the phase change of a solid to a liquid (melting), all of the energy goes into breaking the intermolecular bonds holding the molecules of the solid together, and none of the energy goes into changing the temperature. Thus, during this particular phase of melting, the temperature of the system does NOT change.
What happens to the heat energy which is supplied to the solid once it starts melting?
when solid has already melted and when heat is supplied it starts increasing the temperature of liquid
What happens to an objects temperature when you add heat?
When heat is added to an object, its temperature generally increases as the particles within the object gain more energy and move faster. This increase in temperature is due to the increase in the object's internal energy.
How do object change temperature?
Objects change temperature through the transfer of heat energy. This can occur through conduction, convection, or radiation. When an object gains heat energy, its temperature increases, and when it loses heat energy, its temperature decreases.
Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
When heat is supplied to a solid substance what happens to the energy?
When heat is supplied to a solid substance, the energy is absorbed by the molecules, causing them to vibrate faster and thus increasing their kinetic energy. This increase in kinetic energy allows the solid to eventually change phase into a liquid or gas, depending on the substance and the amount of heat supplied.
Where does heat energy go when temperature is not rising?
During boiling all the heat supplied to the liquid is used up in overcoming the intermolecular forces present among the molecules of the liquid. That is why the temperature of the liquid does not change.
Why is heat of fusion called the latent heat of fusion?
Heat of fusion is called the latent heat of fusion because it is the heat energy required to change a substance from a solid to a liquid phase, or vice versa, without a change in temperature. This heat energy is "hidden" as it is being used to break the intermolecular bonds holding the substance together, rather than increasing its temperature.

What must change in condensation heat energy or temperature?
temperature
The specific heat capacity of a liquid by an electrical heating method?
To determine the specific heat capacity of a liquid using an electrical heating method, you can measure the change in temperature of the liquid when a known amount of electrical energy is supplied. By using the formula Q = mcΔT (where Q is the heat energy supplied, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the temperature change), you can calculate the specific heat capacity of the liquid.
