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

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

Define specific heat capacity and provide examples of intensive properties.

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 $kJ \ mol^{-1}$?

For the reaction ${H_2}_{(g)} + \frac{1}{2}{O_2}_{(g)} \to {H_2}O(\ell)$,given $\Delta C_P = 7.63 \, cal/deg$ and $\Delta H_{25\,^{\circ}C} = 68.3 \, Kcal$,find the value of $\Delta H$ at $100\,^{\circ}C$ (in $Kcal$).

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 $J \ mol^{-1} \ K^{-1}$ ? $(H_2O = 18 \ u)$
