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, 120 J of heat flows into the system and the system does 50 J of work. If the work done by the system is 25 J, the amount of heat in J that flows into the system along the path aeb is

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 , 120 J of heat flows into the system and the system does 50 J of work. If the work done by the system is 25 J, the amount of heat in J that flows into the system along the path aeb is O 95 O 85 60 O 80
