![While shadowing a dentist Evelyn learns that lasers are
the next big thing in "holistic" dentistry, so she
volunteers in a Physics Lab at UCI that. But before they
trust her with lasers, however, they have Evelyn design
the gas power cycle that will power the laser. In Evelyn's
power cycle, air is initially at a pressure of 420 kPa and a
volume of 3 m³. In the first step, the air undergoes
isochoric compression to a pressure of 750 kPa. In the
second step, it undergoes isobaric expansion to a
volume of 7 m³. In the third step, the air undergoes
isothermal expansion until its pressure drops to 420
kPa. In the fourth and final step, the air undergoes
isobaric contraction to a volume of 3 m³. What is the
net heat flow, per cycle, for Evelyn's cycle? [Hint: Draw
