| Thermodynamics | The study of heat |
| Kinetic Theory | Theory that says all matter is made of tiny particles |
| Heat | Transfer or flow of energy |
| Convection | Circulation of thermal energy in a fluid |
| Conduction | Transfer of thermal energy in solids |
| Radiation | Transfer of thermal energy by light |
| Solids | Highly ordered state of matter that holds its shape |
| Liquids | State of matter that cannot be compressed |
| Gases | State of matter that fills its container and that can be compressed |
| Temperature | Average measure of kinetic energy in a substance |
| Kelvin Scale | Scale that is based on absolute zero |
| Celsius Scale | Scale that places b.p. of water at 100° and the f.p. of water at 0° |
