An adiabatic process is experienced by a/an ...... system.

Explain the enthalpy of dilution.

What is the work done when $2 \text{ mole}$ of an ideal gas are expanded isothermally and reversibly from $5 \text{ m}^{3}$ to $10 \text{ m}^{3}$ at $300 \text{ K}$ (in $\text{ kJ}$)? $(R=8.314 \text{ J K}^{-1} \text{ mol}^{-1})$

Identify the equation in which the change in enthalpy is equal to the change in internal energy.

In thermodynamics,a process is reversible when:

Graphically show the total work done in an expansion when the state of an ideal gas is changed reversibly and isothermally from $(P_i, V_i)$ to $(P_f, V_f)$. With the help of a $pV$ plot,compare the work done in the above case with that carried out against a constant external pressure $P_f$.
