Question

In an isothermal process, internal energy of an ideal gas:
  1. A
    Increases
  2. B
    Decreases
  3. C
    Remains constant
    Correct
  4. D
    Depends on pressure

Correct answer

Remains constant

Explanation

For ideal gas, U depends only on T. In isothermal process, T = constant → ΔU = 0 → ΔQ = W.
