A vertical piston-cylinder assembly with 0.2 kg of water is initially a saturated vapor. The piston has a diameter of 10 cm. The cylinder is placed on a hot plate. The piston weighs 39 kg and the atmospheric pressure is 1 atm. Heating occurs at constant pressure and the water expands to a final temperature of 573 K.
Find the pressure inside the cylinder due to the piston and the ambient air.
Find the volume at state 1 and state 2.
Find the energy transfer from the system by work
Explain step by step how you would find the heat transfer. You don't actually have to
solve for the required values, but make sure you explain how you would get the required values and what equations you would need to use.
