Fill in the blanks given below:
$(i)$ Specific heat capacity is the amount of heat required to raise the temperature of $1 \ g$ of a substance by $1^{\circ} C$.
$(ii)$ The unit of heat capacity is $........$.
$(iii)$ Heat capacity is an $........$ property of a substance.
$(iv)$ The amount of heat required to raise the temperature of $1 \ mol$ of a substance by $1^{\circ} C$ is called $........$.

The heat required to raise the temperature of $54 \ g$ of aluminium from $40^{\circ}C$ to $60^{\circ}C$ in $J$ is (molar heat capacity of aluminium in this temperature range is $24 \ J \ mol^{-1} \ K^{-1}$; atomic weight of $Al$ is $27$).

The heat required to raise the temperature of $1 \ mol$ of a substance by $1^{\circ}C$ is called:

Specific heat capacity is defined as:
