The enthalpy of fusion of ice per mole is approximately $...$ $kJ / mol$.

Identify the state functions and path functions out of the following: enthalpy,entropy,heat,temperature,work,free energy.

Calculate work done if $1 \ mole$ of an ideal gas expands isothermally from $2 \ dm^3$ to $2.8 \ dm^3$ against constant external pressure $1 \ atm$. (in $J$)

When the temperature of $2$ moles of an ideal gas is increased by $20^{\circ} C$ at constant pressure,find the work involved in the process. (in $R$)

The change in internal energy $\Delta U$ of an ideal gas depends on:

For which one of the following reactions,$\Delta H$ is not equal to $\Delta E$?
