Consider the PV diagram as shown above when a thermodynamic system changes its state from state a to state b. With the assumption that the system changes only in its internal energy therefore the changes in internal energy along any of the 3 paths are numerically equal. Be mindful of the directions of the arrows. When a system is taken from state a to state b along the path acb , 140 J of heat flows into the system and the system does 60 J of work. If the work done on the system is 20 J when the system returns from b to a along path bda, the amount of heat in J that is either absorbed or liberated is

A fixed mass of gas undergoes changes of pressure and volume as shown below. V When the gas is taken from state P to state R by stages PQ and QR, 8 kJ of heat are absorbed by it and 3 kJ of work are done by it. When the same resultant change is achieved by stages PS and SR, 1 kJ of work is done by the gas. In this case which of the following represents the heat transfer? Select one: 8 kJ of heat are absorbed b. 4 kJ of heat are rejected 12 kJ of heat are rejected O d. 10 kJ of heat are absorbed

The heat pump receives the entire work output (W) of the heat engine. If temperatures.
