Topic: Thermodynamics
For a closed system, difference between the heat added to the system and work done by the gas, is equal to the change in-
- A. Internal energy
- B. Entropy
- C. Enthalpy
- D. Temperature
Answer: A. Internal energy
Explanation: According to the first law of thermodynamics, for a closed system, difference between the heat added to the system and work done by the gas, is equal to the change in internal energy: $\Delta E = Q - W$.
