A heat engine carries 1.70 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 2.2 atm, find the pressure at point 2 in atm.
If the initial pressure at point 1 is 2.2 atm, find the volume at point 3 (in m3).
