Steam is confined in a piston cylinder arrangement with an initial volume of 0.625 cubic meters, an initial temperature of 150 degrees C, and an initial pressure of 16 pounds per square inch. Then the piston is slowly moved so that the steam's volume is decreased by 0.075 cubic meters in an isothermal process. Calculate:

a. the final pressure

b. the work done by the steam

c. the change in the steam's internal energy

d. the change in entropy of the steam

e. whether the total entropy of the universe is increased or decreased by this process

f. draw this on a P-V diagram

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 3.00 L and the pressure is initially 105 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 65.0 J of work is then done on the piston, compressing the gas (in other words, the gas does −65.0 J of work). The work is done very slowly so that the gas maintains a...

This question relates to thermodynamics. in an adiabatic piston cylinder arrangement: if state 1 pressure is known and work is done by the piston to compress a water mixture can the temperature at state 2 be read off the steam tables by using the value of internal energy at state 1 and adding the work to it? If so does this then become the enthalphy i.e. internal energy + work = enthalphy. And then using this enthaphy and the given...

A piston/cylinder device operating in a cycle with steam as the working fluid executes the following steps: (1) steam at 550 kPa and 200 degrees celsius is heated at constant volume to a pressure of 800 kPa. (2) It then expands, reversibly and adiabatically, to the initial temperature of 200 degrees celsius. (3) Finally, the steam is compressed in a mechanically reversible, isothermal process to the initial pressure of 550 kPa. Please show all the steps, and please do not...

In a cylinder/piston arrangement, air is compressed in a reversible polytropic process to a final state of 800 kPa, 500 K. Initially air is at 110 kPa and 25oC. During the compression process heat transfer takes place with the ambient maintained at 25oC. Assume air as an ideal gas (R =0.287 kJ/kg) and has constant specific heats of Cp = 1.004 kJ/kgK and Cv = 0.717 kJ/kgK. If the mass of air in the cylinder is 0.1286 kg, determine a)...

P2-44 A piston-cylinder assembly of total mass 16 lbm is free to move within a housing. Initially the cylinder contains gas at an absolute pressure of 20 Ibf/in^2 and a volume of 0.07 ft^3 and is at rest. The piston is then moved so that the entire assembly accelerates rightward and reaches a final velocity of 7.5 ft/s. During this process, the gas is compressed to a final pressure of 35 Ibf/in^2 The process is adiabatic, and the pressure is...
