A piston- eylinder device contains 2 kg of nitrogen initially at | MP= and 27 C. I con andres.

constant-pressure process until its temperature is 427 C.

(a) Determine the initial volume of the nitrogen, in m'

(b) Determine the final volume of the nitrogen, in m'.

c) Determine the boundary work for the process, in kJ.

For this problem, you may assume that nitrogen is an ideal gas

with gas constant R = 0.2968 kJ/kg-K and constant specific heats
