Heat
heat transfer and energy
Term | Definition |
---|---|
Conduction | transfer heat by directly touching an object to another object |
Convection | The transfer of heat because of the up and down flow of air or fluids due to difference in temperatures |
Radiation | The transfer of heat through a space |
Temperature | a measure of the average amount of kinetic energy |
Absolute zero | temperature point at which all molecular and atomic motion stops |
Equilibrium | reached when the temperature of a substance reaches the same amount of heat |
Thermal insulators | Any object that does not transfer heat well |
Thermal conductor | any object that does transfer heat well |
Thermal Expansion | increase in the volume of a substance due to an increase in temperature |
Heat | Type of energy transferred between objects that are at different |
Kelvin | The temperature scale that shows water boils at 373 and freezes at 273 |
Celsius | The temperature scale that shows water boils at 100 and freezes at 0 |
Fahrenheit | The temperature scale that shows water boils at 212 and freezes at 32 |
Thermometer | A devise or tool used to find the average kinetic energy of a substance |
