Question | Answer |
---|---|
Temperature | a measure of the average kinetic energy of the particles in an object |
How are temperature and an average related? | you need to average the particles in kinetic energy to get temperature |
The temperature of a substance in not determined by | how much of the substance you have |
A thermometer operates of the principle of | thermal expansion |
Thermal expansion occurs when there | is an increase of volume with an increase of temperature |
When the temperature of a substance changes the particles spread out so the entire substance expands | |
Heat | the transfer of energy between objects that are at different temperatures |
Thermal Energy | the total energy of the particles that make up a substance |
Thermal Equilibrium | the point where energy is transferred from the higher temperature object to the lower temperature object, there is no net change in either objects thermal energy |
Conduction | the transfer of thermal energy from one substance to another through direct contact |
Conductors | substance that conduct thermal energy very well |
Insulators | substances that do not conduct thermal energy very well |
Convection | the transfer of thermal energy my movement of a liquid or gas |
Radiation | the energy transfer through matter or space as electromagnetic waves, such as visible light or infrared waves |
