A certain piston assembly contains a certain gas inside. The gas is to be compressed in a series of processes: Process 1: From 180 L to 160 L using an external pressure of 52 atm Process 2: From 160 L to 140 L using an external pressure of 45 atm Process 3: From 140 L to 120 L using an external pressure of 40 atm Process 4: From 120 L to 100 L using an external pressure of 35 atm Process 5: From 100 L to 80 L using an external pressure of 30 atm Determine the net work for the whole process (in kJ).

Question

A certain piston assembly contains a certain gas inside. The gas is to be compressed in a series of processes:

Process 1: From 180 L to 160 L using an external pressure of 52 atm
Process 2: From 160 L to 140 L using an external pressure of 45 atm
Process 3: From 140 L to 120 L using an external pressure of 40 atm
Process 4: From 120 L to 100 L using an external pressure of 35 atm
Process 5: From 100 L to 80 L using an external pressure of 30 atm

Determine the net work for the whole process (in kJ).
