Explain Heat Capacity.
(N/A) The quantity of heat required to increase the temperature of any substance by $1^{\circ}C$ is called the heat capacity $(C)$ of that substance.
$q = C \cdot \Delta T$,where $C$ is the heat capacity.
We can measure the heat supplied by monitoring the temperature rise,provided we know the heat capacity.
When $C$ is large,a given amount of heat results in only a small temperature rise. Water has a large heat capacity,meaning a lot of energy is needed to raise its temperature. $C$ is directly proportional to the amount of substance.
Molar Heat Capacity: The molar heat capacity $(C_m)$ of a substance is the heat capacity for one mole of the substance,defined as the quantity of heat needed to raise the temperature of one mole by one degree Celsius.
$C_m = C / n$
Specific Heat Capacity: The specific heat capacity $(c)$ is the quantity of heat required to raise the temperature of one unit mass of a substance by one degree Celsius.
$q = c \times m \times \Delta T = C \Delta T$,where $m$ is the mass of the substance.
$q = C \cdot \Delta T$,where $C$ is the heat capacity.
