Term
Heat
Definition
a form of thermal energy which causes the particles in a material to increase their kinetic energy (energy in motion)
Term
calorie
Definition
unit used to measure heat, the quantity of heat required to raise the temp. of 1 gram of water 1'C
Term
Joule
Definition
unit for heat, 1 calorie is equal to 4.18J
Term
Temperature
Definition
a measure of the average kinetic energy of the particles in a material/substance
Term
Specific Heat (S.h. or Cp)
Definition
the ability of a material to absorb heat energy, the quantity of heat required to raise the temp. of 1gram of a material 1'C
Term
Absolute Zero
Definition
the temperature at which an objects kinetic energy is minimal; the lowest temp. to which a substance may be cooled.
Term
Heat of Fusion (H of F)
Definition
the quantity of heat required to change one gram of a substance from a solid to a liquid or liquid to a solid
Term
Heat of Vaporization
Definition
quantity of heat required to change 1gram of a substance from a liquid to a gas or a gas to a liquid
Term
Heat Transfer
Definition
the movement of heat energy from warmer objects to cooler objects
Term
Conduction
Definition
method of transferring heat by direct contact (touching) of warmer particles to cooler particles (associated with solids, liquids and gases)
Term
Convection
Definition
method of transferring heat by the movement of particles from warmer areas to cooler areas (associated with liquids and gases)
Term
Radiation
Definition
method of transferring heat without the movement of particles


:the sun transfers energy to earth via this method (elecromagnetic waves)
