Ch10- HEAT(:
Question | Answer |
---|---|
Temperature | a measure of the average kinetic energy of the particles in an object |
How are temperature and an average related? | Temperature is an average measure |
The temperature of a substances is not determined by | how much of a substance you have. Different amounts of the same substance keep the same temperature. |
A thermometer operates of the principle of thermal | expansion |
Thermal Expansion | the increase in volume of a substance due to an increase in temperature. |
Thermal Expansion with bridges | On hot days, the concrete will expand due to thermal expansion. On colder days, the segments will contract. |
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 (expressed in joules) |
Thermal Equilibrium | When two substances with two different temperatures come together and combine into one substance and temperature. |
Conduction | the transfer of thermal energy from one substance to another through direct contact |
Conductors | substances that conduct energy well |
Insulators | substances that do not conduct energy well |
Convection | the transfer of thermal energy by movement of a liquid or gas. |
Radiation | the transfer of energy through matter or space as electromagnetic waves, such as visible light and infrared waves. |
