2. Consider the 3 states labeled A,B, and C on the graph shown below. Each pair of states is connected by one of the four (Adiabatic, Isobaric, Isochoric, or Isothermal) processes. A) What is the process from A to B? How do you know? Sketch the process as accurately as possible. B) How much work is done as the gas goes from state A to state B? How much heating is done as the gas goes from state A to B? Explain. C) What is the process from B to C? How much work is done during this process? D) What is the process from C to A ? How much heating is done during this process? Is there a temperature change during this process? E) This process is an engine. During what parts of the cycle is energy put into the system and during what parts of the cycle is thermal energy exhausted
