5 moles of an ideal gas, initially at P=105 Pa and V=3m3, expand adiabatically until the volume is doubled, then contract in an isobaric process until the volume returns to 3m3, and then is heated in an isochoric process until it returns to the original pressure. The ideal gas is diatomic, so ? = 5/2 R
What is the temperature at the start of this process?
What is the temperature and pressure at the end of the adiabatic step?
How much work was done in the adiabatic step?
What were Q and W for the isobaric step?
What were Q and W for the isochoric step?
What is the efficiency e for this process?
