Chapter 3, Problem 115P(choose chapter or problem)
One kilogram of nitrogen fills the cylinder of a piston-cylinder assembly, as shown in Fig. P3.115. There is no friction between the piston and the cylinder walls, and the surroundings are at \(1 \mathrm{~atm}\). The initial volume and pressure in the cylinder are \(1 \mathrm{~m}^3\) and \(1 \mathrm{~atm}\), respectively. Heat transfer to the nitrogen occurs until the volume is doubled. Determine the heat transfer for the process, in kJ, assuming the specific heat ratio is constant, k=1.4.
