	In a solid the atoms and molecules are packed tightly together. This tightly packed arrangement does not allow for much movement between the particles. ~~Therefore~~ a ~~solid has low~~ kinetic energy~~. In~~ the ~~liquid phase~~ the ~~particles of a substance have~~ more ~~kinetic energy that those~~ in a solid. ~~The atoms and molecules have more movement resulting in~~ a ~~higher~~ kinetic energy.		In a solid the atoms and molecules are packed tightly together. This tightly packed arrangement does not allow for much movement between the particles. At a given temperature the kinetic energy is determined by only the temperature, not the state. More heat generally means more movement in the molecules. What changes in comparison between a solid and a liquid (for example) is the particle arrangement and the potential energy. During melting at a constant temperature such as at melting point, the energy added to the system does not increase the kinetic energy, but instead only affects potential energy.

	In the change of state from solid to liquid there is energy required to overcome the binding forces that maintain its solid structure. This energy is called the heat of fusion.		In the change of state from solid to liquid there is energy required to overcome the binding forces that maintain its solid structure. This energy is called the heat of fusion.
	In the change of state from liquid to solid energy is given off. The energy given off by this transition is the same amount as the energy required to freeze the matter.		In the change of state from liquid to solid energy is given off. The energy given off by this transition is the same amount as the energy required to freeze the matter.

	In a liquid the atoms and molecules are moving less than they would in the gas state. Therefore the gaseous state has a higher kinetic energy than the liquid state. This is due to the fact that atoms and molecules in liquids are still packed together more closely than the atoms and molecules in a gas.		In a liquid the atoms and molecules are moving less than they would in the gas state. Therefore the gaseous state has a higher kinetic energy than the liquid state. This is due to the fact that atoms and molecules in liquids are still packed together more closely than the atoms and molecules in a gas.
	In the change of state from liquid to gas there is energy required to overcome the bonds between the more closely packed atoms and molecules. This energy is called the heat of vaporization.		In the change of state from liquid to gas there is energy required to overcome the bonds between the more closely packed atoms and molecules. This energy is called the heat of vaporization. Note that in this process the additional heat is contributing to the system's potential energy as it overcomes the bonds between molecules.
	In the change of state from gas to liquid energy is given off by the transition. This energy is equal in magnitude to the energy required to transition from liquid to gas.		In the change of state from gas to liquid energy is given off by the transition. This energy is equal in magnitude to the energy required to transition from liquid to gas.
