3. Energy- ability to do work or cause change. Kinetic Energy- energy of motion. An object with more kinetic energy, the particles move faster and farther apart. An object with less kinetic energy, the particles move slower and stay closer together. Thermal Energy- total kinetic energy and potential energy of the particles. The warmer the substance, the more thermal energy. Temperature- average kinetic energy of individual particles. Thermal=Total/ Temperature=Average Heat- movement of thermal energy from higher temperature to lower temperature

4. Amount of heat required to raise temperature of a 1g of a substance 1 Degrees Celsius Metals and sand have low specific heat. Water has a high specific heat.

5. Change of State- matter can change states when thermal energy is absorbed of released. Amorphous solids get softer when heated. Melting- change from solid to liquid. Melting Point- temperature at which change occurs. Freezing- change from liquid to solid. Liquids cool, particles slow, crystals form Freezing Point- temperature at which change happens. Particles in liquids have more energy than particles in solids

6. Sublimation- surface particles gain enough energy to become a gas. Dry Ice- When dry ice becomes gas, it absorbs thermal energy from water vapor.

7. Vaporization- change from liquid to gas. Temperature has no change. Substance gains thermal energy. Particles move faster and turn into gas. It takes place below surface of liquid. Water boils at 100 Degrees Celsius

8. Faster particles evaporate, slower particles stay Perspiration- cooling effect Condensation- change of matter from gas to liquid Temperature doesn’t change. There is a decrease in energy. Condensation shows up on outside of glass.
