Please answer and no reject ,need max in 30 minutes thank y It is reported that a gas is taken through a series of five operations, finally arriving at the same temperature, pressure, and volume it possessed originally Step 1: the system absorbs 220 kj of heat and performs 300 k) of work on the surroundings Step 2: the system loses 110 kj of heat while he volume constant Step 3: 110 kj of work is done on the system and it absorbs 60 kj of heat Step 4: the system loses 160 kg of heat while the volume remains constant Step Sithe system absorbs 290kj of heat and does 220 kj of work on the surroundings Can you say whether this report is corrected or not?
