Part A: To obtain a higher pressure the volume in the cyllinder must decrease, so the correct picture would be,
A.
Part B. True statement
Part C. The new volume V2 = P1V1/P2
with,
P1 = 625 mmHg = 0.82237 atm
V1 = 215 ml
P2 = 1.3 atm
we get
V2 = 0.82237 x 215/1.3 = 136.01 ml

A vertical piston-cylinder contains 1.5 lbm of air. The piston has a mass of 6 Ibm and a face area of 10 in2. The air initially occupies a volume of 30.6 in3 and has a specific internal energy of 225 BTU/lbm. The atmosphere exerts a pressure of 1 atm on the top of the piston. Heat transfer occurs slowly during the process between the air in the piston and the surroundings, and the volume of the air decreases to 15.0...

A 19.0- L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.2 atm . Enough weight is suddenly removed from the piston to lower the external pressure to 1.6 atm . The gas then expands at constant temperature until its pressure is 1.6 atm . The change in the internal energy of a system, ΔE , for an isothermal expansion of an ideal gas is 0. Use this information in your calculations...

Consider a piston-cylinder device (system) that contains 0.06 m3 of air at 300 kPa and 125 ̊C. (a) If the volume of air in the device increases to 0.15 m3 while the pressure remains constant, determine the work done by the system during the process. (b) If as a result of heat transfer to the surrounding, the pressure and temperature in the device drop to 240 kPa and 55 ̊C, respectively, and the piston is held such that the volume...
