HEAT CAPACITY
The heat capacity of a body is the amount of heat that must be supplied
to the body to increase its temperature by 1 oC.
SPECIFIC HEAT CAPACITY, c
The specific heat capacity of a substance is the amount of heat that
must be supplied to the increase the temperature by 1 oC for a mass
of 1 kg of the substance.
APPLICATIONS OF SPECIFIC HEAT CAPACITY
COOKING POT
§ Copper has a
smaller specific heat capacity.
§ Therefore, the
copper base heats up very quickly.
§ The handle is
made of a material which has a larger specific heat capacity.
§ Therefore, it
will not become too hot even if heat is absorbed.
THE COOLING SYSTEM OF A CAR ENGINE
§ Water which
has a high specific heat capacity is suitable to use as cooling agent in car
radiator as it can absorb a large quantity of heat with little increase in
temperature.
