Temperature | a measure of the average kinetic energy of particles in an object. |
How are temperature and an average related | Temperature is an average. |
The temperature of a substance is not determined by | how much of the substance you have. |
A thermometer operates on the principle of thermal | expansion |
Thermal Expansion occurs when | the temperature of the substance increases. |
A bridge has gaps in it | to prevent buckling of the bridge when thermal expansion occurs. |
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 | no net change in either objects thermal energy occurs, when both objects have 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 a gas. |
Radiation | the transfer of energy through matter or space as electromagnetic waves. |
