When the molecules in a body move with increased speed is it possible that the body will change from a gas to liquid or gas to a solid or liquid to a solid or liquid to a gas?
Molecules in a solid are tightly packed together and therefore have very low average kinetic energy. However, if you add energy to the system you are increasing the random motion of molecules and the intermolecular distance within the molecules increases thereby changing the substance into a liquid state. Same is true when going from liquid to gaseous state of matter. So only the liquid to gas phase change could occur, if all other conditions remain…
Lets assume the molecules in the liquid have a certain kinetic energy: E = 0.5mv2 If the liquid is heated, more energy is given to the molecules so their kinetic energy is increased. If their kinetic energy is increased, and their mass remains constant, then their velocity must have also increased according to the above equation. Answer: they move faster
In a liquid, the molecules are moving about. During evaporation, some molecules near the surface have enough kinetic energy to escape the bonds within the liquid. When the liquid is heated more energy is supplied to the molecules giving them increased energy and more are able to escape the bonding in the liquid
Gas molecules have fewer constraints on their location, than liquid molecules. Molecules in a liquid have to remain in contact with the other molecules of the liquid, and are limited to a specific volume. Gas molecules can go anywhere, they are not connected to anything. So with more possible locations, gas molecules represent a state of higher entropy or disorder.
The phase change for liquid to gas is vaporization, which includes evaporation and boiling. Evaporation - The change of liquid molecules on the surface of a liquid to a gas. Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state?
When the temperature of a particular solid exceeds its' melting point, then it starts melting. This increased temperature increases the kinetic energy of molecules of that solid and hence, those molecules overcome the force of attraction between themselves and begin to change their state. Solids can change to either liquid state or gaseous state.
In order for molecules in a solid state to change to a liquid state, the substance needs to be heated. An increase in temperature causes more molecular movement (this leaves more space between each molecule) which results in what we see as the physical change from solid to liquid and then eventually liquid to gas.
A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of…
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
The molecules state of being changes from that of gas to that of being a liquid. The gaseous substance molecules has much more energy in it. But as the energy escapes or slows down, the molecules stop moving so much and there for bond better causing gas to change to liquid; and liquid to change to a solid. Solid particles are those whose atoms and molecules move very slightly and contain little energy.
This physical phenomenon is called melting; the intermolecular forces decrease. xxx The intermolecular forces don't decrease. The heat energy being added to melt the ice causes a change in the molecular motion of the water. This increased molecular motion breaks the bonds and the water becomes a liquid. The bonds, aka intermolecular forces' are overcome by the increased energy in the water molecules allowing free motion of the water molecules as they now slide past…
