Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. T…

A frictionless piston–cylinder device, shown in initially contains 0.01 m3 of argon gas at 400 K and 350 kPa. Heat is now transferred to the argon from a furnace at 1200 K, and the argon expands isothermally until its volume is doubled. No heat transfer takes place between the argon and the surrounding atmospheric air, which is at 300 K and 100 kPa. Determine the maximum work that can be produced during this process.

Nitrogen at an initialstate of 300 K, 150 kPa, and 0.2 m3 is compressed slowly in anisothermal process to a final pressure of 800 kPa. Determine the work doneduring this process. Also, explain the negative sign in the answer.

An ideal gas is compressed isothermally from 100 kPa to 170 kPa. The percent increase in the density of this gas during this process is (a) 70% (b) 35% (c) 17% (d) 59% (e) 170%
