1. Given that H is a function of T and V, that is H(T,V), derive the following expression: dH = C, +V ƏT, dT + dV Where H is the enthalpy of the system, and all other variables have the usual meaning. Use the above expression to calculate the enthalpy change (in J) for 1 mol of an ideal gas when is it is compressed from T, = 273 K, P, = 1 atm and V, = 12 L to P2 = 10 atm and V2 = 6 L. For an ideal gas, Cy = 1.5 R. %3|
