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

The correct order of molar heat capacities measured at $298 \ K$ and $1 \ bar$ is:

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

The molar heat capacity of water at constant pressure is $75 \ J \ K^{-1} \ mol^{-1}$. When $1.0 \ kJ$ of heat is supplied to $100 \ g$ of water which is free to expand,the increase in temperature of water is $...... \ K$.

Which graph represents the relationship between heat capacity at constant pressure $(C_p)$ and temperature $(T)$ for a monatomic ideal gas?

What will be the $\Delta U$ value, when one mole of oxygen $(O_2)$ is heated from $-20^{\circ} C$ to $40^{\circ} C$ at constant volume (in $J$)? (Molar heat capacity for oxygen $\simeq 20.8 \ J \ mol^{-1} \ K^{-1}$)
