Nitrogen with a mass of 1.5 kg and molar mass of 28 kg/kmol, is compressed
isothermally and reversibly from 103 kPa and 20°C to 425 kPa. Calculate the
work done and the heat flow during the process.
Air at 101.3 kPa and 22°C has a volume of 0.0156 m³ in a cylinder and is
compressed adiabatically and reversibly by a piston to 685 kPa. Calculate the
final temperature, the final volume, and the work done on the air. Assume that
R = 0.287 kJ/kg.K and Cp = 1.005 kJ/kg.K.
A quantity of nitrogen in a perfectly insulated cylinder (so that there is no heat
flow to or from the cylinder walls), expands from 355 kPa and 200°C to a
volume of 0.093 m³. If the original volume were 0.034 m³, calculate the work
done during expansion. Take Cy= 0.741 kJ/kg.K and y = 1.4.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdec28509-217b-4853-aae8-2524465e3ccc%2Fe4289640-524d-4c56-8fff-948fbcdde1b0%2Fc756hzw_processed.jpeg&w=3840&q=75)
