Thermal Physics Section 3

Conservation of energy

Change in thermal energy is the same as the heat transferred.

calorimeter

a measuring instrument that determines quantities of heat

Four states of matter

solid, liquid, gas, plasma

Melting point

the temperature at which matter changes from solid to liquid

boiling point

the temperature at which a liquid boils at sea level

Heat of fusion

heat required to melt

Heat of vaporization

Heat required to change a liquid to a gas
