3.5 I can apply the 1st Law of TD for closed systems containing solids, liquids, vapors, and/or gases using appropriate methods
2-kg of water vapor is contained in a piston-cylinder device at 1.5 MPa and 500°C. Heat is added to the steam until the temperature rises to 600°C, and the piston moves to maintain a constant pressure. Determine the amount of heat transfer during this process (in either kJ/kg or kJ). There are changes in kinetic or potential energy.
