Two moles of an ideal gas is expanded isothermally and reversibly at $300 \ K$ from $1 \ L$ to $10 \ L$. The enthalpy change in $kJ$ is

The heat of combustion of ethanol in a bomb calorimeter at $25\,^oC$ is $-670.48\, K\,cal\, mol^{-1}$. Find the value of $\Delta U$ in $K\,cal$ for the reaction at $25\,^oC$.

For a chemical reaction,when does $\Delta H = \Delta U$ occur?

An ideal gas expands from $1 \times 10^{-3} \ m^{3}$ to $1 \times 10^{-2} \ m^{3}$ at $300 \ K$ against a constant external pressure of $1 \times 10^{5} \ Nm^{-2}$. The work done is:

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

Which of the following is $NOT$ an intensive property?
