What happens as a solid begins to change to a liquid?
The internal energy of the item increases, and the molecules become less ordered.
When a liquid becomes a solid where does the heat energy in the liquid go?
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 water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
When ice starts to melt what happens to the temperature until it completely changes to all water?
During a change of state (phase) there is only a change in the potential energy of the molecules, not the kinetic energy. The energy is used by the molecules to rearrange themselves into positions they have in the liquid state.
why is there no further rise in temperature when you heat a liquid at its boiling point?
The extra heat energy is being absorbed to change the liquid molecules into gas molecules by breaking the intermolecular attractions holding the molecules close together as a liquid.

What happens to a liquid . When it releases energy?
The liquid cools down. Its molecules move more slowly.
Does the temperature of a liquid change due to evaporation?
Yes, it decreases. This is because the molecules of the liquid which have higher kinetic energy escape from the liquid, leaving the liquid with molecules having lower kinetic energy. The temperature of any substance is proportional to the kinetic energy of its molecules.

What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.
To change liquid to a soild?
To change a solid to a liquid you need to add energy. The energy makes the molecules vibrate faster and they find it easier to break bonds holding them to the molecules directly next to them and form new bonds to other molecules.
How does a liquid change into a gas when it is heated?
The molecules absorb more energy, more speed and can be released from the liquid.
What is the molecules at the surface of a liquid absorb enough energy to change to a gas?
vaporization

What happens to molecules when they change from one state of matter to another?
the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)
