The energy required to increase the temperature of $180 \ g$ of liquid water from $10^{\circ} C$ to $15^{\circ} C$ is $3765 \ J$. What is $C_{p}$ of water in $J \ mol^{-1} \ K^{-1}$ ? $(H_2O = 18 \ u)$

$A_{(g)} \to 2B_{(g)}$; $\Delta_rH = 20 \ kJ/mol$ at $300 \ K$. If $C_{p,m}(A) = 20 \ J \ K^{-1} \ mol^{-1}$ and $C_{p,m}(B) = 5 \ J \ K^{-1} \ mol^{-1}$,which of the following statements is correct?

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

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 $24 \, J \, mol^{-1} \, K^{-1}$.

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

$4.48 \ L$ of an ideal gas at $1 \ atm$ and $273 \ K$ requires $12 \ cal$ to raise the temperature by $15 \ ^\circ C$ at constant volume. The $C_p$ of the gas is $... \ cal \ mol^{-1} K^{-1}$.
