In an isothermal expansion of an ideal gas,
Select one or more:
  • a)
    ΔH = 0
  • b)
    ΔQ = 0
  • c)
    ΔW = 0
  • d)
    ΔU = 0
Correct answer is option 'A,D'. Can you explain this answer?
Verified Answer
In an isothermal expansion of an ideal gas,Select one or more:a)&Delta...
For one mole of an ideal gas

⇒ dU = CVdT
For isothermal process, T is constant

Also ΔH = ΔU + Δ(pV)
pV = RT

= ΔU + RΔT
ΔH = 0.
The correct answers are: ΔU = 0, ΔH = 0
