Physics · Thermodynamics
A given quantity of gas is taken from state A to state C reversibly by two paths: directly along A → C, and via A → B → C. During the process A → C, the work done by the gas is 100 J and the heat absorbed is 150 J. If during the process A → B → C the work done by the gas is 30 J, the heat absorbed is:
- 120 J
- 280 J✓
- 3220 J
- 4280 J
