2.18 (a) First, as always, simplie the energy balance. Potential and kinetic energy effects can be neglected. Therefore, the energy balance is Since, this system contains water, we can the use the steam tables. Enough thermodynamic properties are known to constrain the initial state, but only one thermodynamic property is known for the final state: the pressure. Therefore, the pressure-volume relationship will be used to find the specific volume of the final state. Since the specific volume is equal to the molar volume multiplied by the molecular weight and the molecular weight is constant, the given expression can be written This equation can be used to solve for C2. Using
