Extracted text: Note: This page should be the first of your report Q1) A piston-cylinder assembly contains 2.0 lbm of air at a temperature of 540 °R and a pressure of 1 atm. The air is compressed to a state where the temperature is 840 °R and the pressure is 6 atm. During the compression, there is a heat transfer from the air to the surroundings equal to 20 Btu. Using the ideal gas model for air, determine the work during the process, in Btu.
