thermo dynamics

1000 800 Pressure-p, kPa 600 400 200 0 0 10 30 40 20 Volume - V, dm The working fluid is an ideal gas. A process in the diagram is bounded by two states, which are represented by circular markers. Unless it is stated, a process can go both directions. Select the correct statements. Select one or more: Independently of the direction, one of the processes is isochoric heat addition During the second process (in the middle), there is a heat transfer between system and surroundings (either heat addition or heat removal). One of the processes has zero boundary work If this diagram represents the pressure, and Volume values of a steady flow device, one of the processes show zero work

Answer 1

Dear student,

Inorder to answer the below statements, we need to know process involved in the given PV diagram.

Here there are three process involved,

1. Constant pressure process (isobaric process)

2. Constant volume process (isochoric process)

3.Costant temperature process (isothermal process)

Brief description of each statements given below,
