Answer :
- The internal energy change for the gas during compression, given the work done is 5000 kJ and heat interaction is 2000 kJ, is -3000 kJ. Option c is correct answer.
1. Given:
- Work done during compression (W) = 5000 kJ
- Heat interaction (Q) = 2000 kJ
2. The First Law of Thermodynamics states: ΔU = Q - W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.
3. Calculate the internal energy change:
- ΔU = Q - W
- ΔU = 2000 kJ - 5000 kJ
- ΔU = -3000 kJ
The internal energy change for the gas during compression is -3000 kJ. Option c is correct answer.
