Question

A heat engine carries 2.60 mol of an ideal monatomic gas around the cycle shown in the figure. Process 1-2 takes place at constant volume and takes the gas from 300 K to 600 K, process 2-3 is adiabatic and takes the gas from 600 K to 455 K, and process 3-1 takes place at a constant pressure and returns the gas to 300 K. Compute the heat Q for the whole cycle. Compute the change in internal energy DeltaE for the cycle as a whole.Calculate the work done by the gas for the cycle.If the initial pressure at point 1 is 1.4 atm, find the pressure at point 2 in atm. If the initial pressure at point 1 is 1.4 atm, find the volume at point 3 (in m3).

Answer 1
