OF HEAT (HEAT ENERGY)
kilocalorie (kcal) - 1,000 calories
British Thermal Unit (BTU) - amount of heat required to raise 1 lb. of water by 1 oF.
specific heat - amount of heat (# calories) needed to raise 1 g of a substance by 1 oC. (water = 1.0)
of fusion -
amount of heat (# calories) needed to change 1 g of a substance from solid
of vaporization -
amount of heat (# calories) needed to change 1 g of a substance from
WAYS TO TRANSFER HEAT (HEAT ENERGY)
There are 3 ways in which heat (heat energy) can be moved.
1) conduction- flow of heat energy through a medium from molecule to molecule.
2) convection - mass movement of heat energy.
flow of energy as electromagnetic waves, with no transferring medium; when
