| Specific heat | The amount of thermal energy needed to raise the temperature of 1 gram of material by 1 degree Celsius. |
| Objects with high specific heat... | ...warm up and cool down slowly because they require more energy to raise their temperature. |
| Objects with low specific heat... | ...warm up and cool down quickly because they require less energy to raise their temperature. |
| Metals | Low specific heat |
| Sand | Low specific heat |
| Water | High specific heat |
| Cork | High specific heat |
| Rubber | High specific heat |
| Wood | High specific heat |
| Formula for finding Thermal Energy change of an object | Q=M x C x /\T |
| What does the Q variable signify? | Change in thermal energy (Joules) |
| What does the M variable signify? | Mass of the substance |
| What does the /\T variable signify? | Change in the substance's temperature |
| What does the C variable signify? | Specific heat of the substance |
| What is water's specific heat? | 4.18 degrees J/g*C |
| Thermal expansion | The expansion of matter when it is heated. As the thermal energy of matter increases, its particles usually spread out, causing it to expand. |
| Method to convert Fahrenheit to Celsius | C = (F - 32) x 5 / 9 |
| Method to convert Celsius to Fahrenheit | F = (C x 9 / 5) + 32 |
