Potential energy is ______ energy stored
Chemical potential energy ________ as the particles get farther apart and _______ as the particles become closer together increases decreases
The total kinetic and potential energy of an object is a measure of its _______ Thermal energy
An objects state of matter can be changed by adding or removing Thermal energy
Adding thermal energy to an object causes the particles to move faster (increasing ______ energy), or to get farther apart (Increasing ______ energy) or to do both. Kinetic, Potential
When enough thermal energy is added, a solid changes to a _____ this process is called _____ liquid-melting

When you add ______ energy to ice, the temperature of the ice increases, which means that the ______ energy of the water molecules increases Thermal-kinetic
At the ________ point of water (0) water molecules vibrate so fast that they begin to move out of their places and melting occurs melting
Once a substance melts, the average ______ energy of its particles begins to increases again as more ______ energy is added. Kinetic-thermal
When water reaches its _____ point (100) liquid water begins to change water_______ Boiling- vapor
When thermal energy is removed from water vapor it _______ at 100 and the liquid water ______ at 0 Condenses-freezes
