PHYSICAL PROPERTIES OF MATERIALS

Specific Heat
The quantity of heat energy required to increase the
temperature of a unit mass of material by one degree
To determine the energy to heat a certain weight of
metal to a given elevated temperature:
H = C W (T 2 - T 1 )
where H = amount of heat energy; C = specific heat
of the material; W = its weight; and (T 2 - T 1 ) = change
in temperature
