$4.48 \ L$ 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 $... \ cal \ mol^{-1} K^{-1}$.

Molar heat capacity $(C_p)$ of water at constant pressure is $75 \ J \ K^{-1} \ mol^{-1}$. The increase in temperature (in $K$) of $100 \ g$ of water when $1 \ kJ$ of heat is supplied to it is

The ratio of the heat capacities $C_p / C_V$ for one mole of a gas is $1.67$. The gas is

Heat capacity $(C_{p})$ is an extensive property but specific heat $(c)$ is an intensive property. What will be the relation between $C_{p}$ and $c$ for $1 \ mol$ of water?

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 molar heat capacity of water in equilibrium with ice at constant pressure is.....
