AIPMT 2012 Mains Physics - Heat and Thermodynamics Question 55 English

If Q₁, Q₂, Q₃ indicate the heat absorbed by the gas along the three processes and $$\Delta $$U₁, $$\Delta $$U₂, $$\Delta $$U₃ indicate the change in internal energy along the three processes respectively, then

Q₁ > Q₂ > Q₃ and $$\Delta $$U₁ = $$\Delta $$U₂ = $$\Delta $$U₃

Q₃ > Q₂ > Q₁ and $$\Delta $$U₁ = $$\Delta $$U₂ = $$\Delta $$U₃

Q₁ = Q₂ = Q₃ and $$\Delta $$U₁ > $$\Delta $$U₂ > $$\Delta $$U₃

Q₃ = Q₂ = Q₁ and $$\Delta $$U₁ > $$\Delta $$U₂ > $$\Delta $$U₃
