In a quasi-static isobaric expansion, 540 J of work are done by the gas. The gas pressure is 0.90 atm and it was originally at 15.0 L. If the internal energy of the gas increased by 70 J in the expansion, how much heat (in J) does the gas absorb?
This question deals with a cylinder, which is upright. Here are the facts for the problem. Can you please help me with a clear diagram and then the right equations for net work and heat? There is a massless and frictionless piston inside the cylinder with two stops which prevent movement down the cylinder. But, the cylinder can still move upward. Under the Below the piston is 5 kg of water, 50% of which (by mass) is initially vapor at 120°C. Heat is gradually added to the water until the water reaches a final state of 400°C. The atmospheric pressure is 500 kPa. The stops don't affect the area. (1) Draw a P-V diagram for the process, which includes the isotherms at states 1 and 2. (2) A what temperature does the piston first lift off? At what temperature has the liquid turned to vapor? (3) What is the net work and heat transfer between the system and the surrondings between states 1 and 2. Are these transfers going into or out of the system?
