1. Saturated liquid water at 1.0 MPa is inside a pistoncylinder device, which is heated until all of the water is vaporized. Find the amount of heat transfer needed for this process.
2. Find the change in enthalpy and the change in internal energy of nitrogen in aprocess from 30 degrees C to 200 degrees C. (Take the pressure at atmospheric conditions.)
