The Nature of Heat
FME: Chapter Six, Section Two
Term | Definition |
---|---|
heat | thermal energy that is transferred from one subtance to another. |
conduction | the transfer of heat between particles within a subtance. (Think: direct contact) |
convection | the transfer of heat by the movement of currents within a fluid. (Think: liquids and gasses) |
convection current | a current caused by the rising of heated fluid and sinking of cooled fluid. |
radiation | the transfer of energy by electromagnetic waves. |
direction of heat | heat is transferred from a warmer subtance to a cooler subtance. |
conductor | a material that easily transfers heat between its particles. |
insulator | a material that does not easily transfer heat between its particles. |
specific heat | the amount of heat required to raise the temperature of one kilogram of a subtance by one kelvin. (Think: each subtance requires different amount of heat to change its temperature.) |
examples of conductors | silver, stainless steel, iron, gold (Think: metals) |
examples of insulators | wood, wool, paper, cork, air, gasses, down feathers, fiberglass |
