Temperature | A measure of the average kinetic energy of the particles in an object |
How are temperature and an average related? | It is an approximation of all the particles since they all do move at the same speed. |
The temperature of a substance is not determined by _________________? | How much you have |
A Thermometer operates of the principle of thermal __________? | Expansion |
Thermal Expansion occurs when ___________________? | The Temperature rises. |
A bridge built over a river or interstate has joints in it because | When the temperature rises the bridge expands so it needs somewhere to go |
Heat | The Transfer of energy between objects that are at different temperatures |
Thermal Energy | The total energy of particles that make up an object |
Thermal equilibrium | The point when two objects reach the same temperature |
Conduction | The transfer of thermal energy from one substance to another through direct contact |
Conductors | Substances that conduct thermal energy very well |
Insulators | Substances that do not conduct thermal energy very well |
Convection | The transfer of thermal energy by the movement of a liquid or gas |
Radiation | The transfer of energy through matter or space as electromagnetic waves such as visible light or infrared waves |
