State the units of specific heat capacity and molar heat capacity.

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 $........$.

Define specific heat capacity and provide examples of intensive properties.

$20 \ cal$ of heat is required to increase the temperature of a $15 \ g$ piece of $Al$ metal from $25^{\circ}C$ to $30^{\circ}C$. Calculate the heat capacity,specific heat capacity,and molar heat capacity of the $Al$ piece. (Given: Atomic mass of $Al = 27 \ g \ mol^{-1}$)

For a reaction $H_{2(g)} + \frac{1}{2}O_{2(g)} \longrightarrow H_2O_{(l)}$; $\Delta C_p = 32 \ J \ K^{-1}$,$\Delta H$ at $27 \ ^oC = -285.8 \ kJ \ mol^{-1}$. What will be the value of $\Delta H$ at $127 \ ^oC$ in $kJ \ mol^{-1}$?

Calculate the number of $kJ$ of heat necessary to raise the temperature of $60.0 \, g$ of aluminium from $35^{\circ} C$ to $55^{\circ} C$. Molar heat capacity of $Al$ is $24 \, J \, mol^{-1} \, K^{-1}$.
