Options
(a) internal energy increases
(b) internal energy decreases
(c) internal energy remains same

Correct Answer:
internal energy remains same
Explanation:
Internal energy change (ΔE) is a function of temperature. So for constant temperature, ΔE is also zero i.e., internal energy remains same. [ΔE ∝ T]
