16 terms
Terms | Definitions |
|---|---|
 Thermal Energy | Heat energy measured in joules |
| Formula for heat energy | Q=mass x change in temperature x specific heat capacity |
| calorie | heat required to raise the temperature of 1kg of water by one degree celsius |
| Kilocalorie | 1000 calories |
| Calorie | same as a kilocalorie, used as the "food unit" of calories |
| Temperature | The average kinetic energy of molecules-fast moving molecules have more kinetic energy(warmer) |
| Celsius | Metric unit for temperature |
| Fahrenheit | English unit for temperature |
| Kelvins | Another temperature scale used in science. 0 degrees Kelvin is known as absolute zero |
| Thermometer | Tool used to measure average kinetic energy |
| Specific Heat Capacity | An objects ability to store heat energy. |
| Calorimeter | Tool used to measure the specific heat of a substance. |
| Absolute Zero | The theoretical temperature at which the amount of kinetic energy is zero. Absolute zero has a value of 0 degrees Kelvin or -273 degrees Celsius |
| Solids | Particles are packed close together |
| Liquids | Particles have more space between them |
| Gases | Particles are spaced far apart. Gases have the highest kinetic energy of all three forms of matter. |
