An ideal gas at constant temperature and pressure expands and its
Options
(a) internal energy increases
(b) internal energy decreases
(c) internal energy remains same
(d) endropy increases and then decreases
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]
