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

The heat required to raise the temperature of a body by $1 \, K$ is called

What is the value of ${\left[ {\partial U/\partial T} \right]_V}$ for $He$ gas?

$20 \ cal$ 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 $Al = 27 \ g \ mol^{-1}$)

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 $27$).

When a $60 \, W$ electric heater is immersed in a gas for $100 \, s$ in a constant volume container with adiabatic walls,the temperature of the gas rises by $5^{\circ} \, C$. The heat capacity of the given gas is $......... \, J \, K^{-1}$ (Nearest integer).
