1.State the First Law of Thermodynamics and write its sign conventions for heat supplied and work done.
2.Derive the relation $C_p - C_v = R$ (Mayer's relation) for an ideal gas.
3.Write expression for work done in an Isothermal process ($W = nRT \ln(V_2/V_1)$).
4.Write expression for work done in an Adiabatic process ($W = \frac{nR(T_1 - T_2)}{\gamma - 1}$).
