During a constant pressure, nonflow (closed system) process, a gas loses 103 BTUs of heat to the surroundings while it's volume changes from 2.2 ft3 to 0.7 ft3. If the temperature of the gas decreases by 7 oF and the system contains 3.3 lbm of gas, find the absolute pressure of the system in lbf/in2. cV for this gas is 0.229 BTU/lbm-oF. (Hint: For this process, ∆U = mcV∆T even though the process is not carried out at constant volume).
State your answer to one decimal place.
I will rate you.

A gas undergoes a process in a piston–cylinder assembly during which the pressure-specific volume relation is pv1.1 = constant. The mass of the gas is 0.4 lb and the following data are known: p1 = 160 lbf/in.2, V1 = 1 ft3, and p2 = 390 lbf/in.2 During the process, heat transfer from the gas is 2.1 Btu. Kinetic and potential energy effects are negligible. Determine the change in specific internal energy of the gas, in Btu/lb.

A gas undergoes a process from state 1, where p1 = 60 lbf/in.2, v1 = 6.0 ft3/lb, to state 2 where p2 = 85.1 lbf/in.2, according to pv1.3 = constant. The relationship between pressure, specific volume, and internal energy is u = (0.2651)pv - 95.436 where p is in lbf/in.2, v is in ft3/lb, and u is in Btu/lb. The mass of gas is 10 lb. Neglecting kinetic and potential energy effects, determine the heat transfer, in Btu. Entry field...

Ammonia is contained in a piston-cylinder assembly. The ammonia undergoes a reversible, isobaric process from an initial pressure of 30 lbf/in2 and volume of 4 ft3/lb to a final temperature of 70° F. The mass of ammonia is 0.35 lb.

A system of ideal gas has an initial pressure of 114 kPa and occupies a volume of 6.00 liters. Doubling the system’s absolute temperature by means of a constant-pressure process would require an amount of work W. Instead, you decide to double the absolute temperature by carrying out two processes in sequence, a constant-pressure process followed by a constant-volume process. In this case, the total work done in the two-process sequence is W/2. Calculate the final pressure of the system....
