| Fahrenheit scale - | the most common temperature scale in the United States. |
| Celsius scale - | the temperature scale used in most of the world. |
| Kelvin scale - | is the temperature scale commonly used in physical science |
| Absolute zero - | is the temperature when no more energy can be removed from the matter. |
| Temperature | is a measure of the average kinetic energy of the individual particles. |
| Thermal energy | is the total energy of all the particles. |
| Heat | is the thermal energy moving from a warmer object to a cooler object. |
| In process of conduction, | heat is transferred from one particle of matter to another without the movement of matter itself. |
| Convection | transfers heat within a fluid(a liquid or a gas) by the movement of currents. |
| Radiation | is the transfer of energy by electronic waves. |
| Insulator | is the material that does not conduct heat well. |
| Specific heat | is the amount of energy required to raise the temperature of 1 kg of a substance by 1k. |
