Explain the internal energy as a state function.

Calculate the work done in joule if $1 \ mole$ of an ideal gas is compressed from volume $24 \ dm^3$ to $13 \ dm^3$ at a constant external pressure of $3 \ bar$. (in $J$)

During the reversible isothermal expansion of an ideal gas,the change in internal energy is......

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

Assume each reaction is carried out in an open container. For which reaction will $\Delta H = \Delta E$ ?
