ME/CH EN 2300 Homework # 4 Due Wednesday, Feb. 7 Note: Please list which section of the class you are in (ME EN or CH EN) on your assignment #1 (4-15) A mass of 2.4 kg of air at 150 kPa and 12 o C is contained in a gas-tight, frictionless, piston-cylinder device. The air is now compressed to a final pressure of 600 kPa. During the process, heat is trasfered from the air such that the temperature inside the cylinder remains constant. Calculate the work input during this process. (Answer = 272 kJ). #2 (4-23) Determine the boundary work done by a gas during an expansion process if the
