thermal energy transfer
Question | Answer |
---|---|
conduction | thermal energy heat transferred when two objects touch works best in solids . |
convection | thermal energy heat transferred by the circulation or movement of a liquid or gas works best in fluids |
fluid | a liquid or gas that has the ability to flow |
radiation | thermal energy heat transferred through matter or empty space by electromagnetic waves no direct contact needed |
conductor | a material that transfers thermal or electrical energy very well |
insulator | a material that does not transfer thermal or electrical energy very well |
thermal expansion | an increase in the size of a substance due to an increase in the temperature of the substance |
thermal equilibrium | the point at which two objects that are touching reach the same temperature |
thermal energy | energy an object has depending on the motion of it atoms total kinetic energy |
thermal contraction | a decrease in the size of a substance in response to a decrease in the temperature of the substance |
