Question

Starting with the same initial conditions, an ideal gas expands from volume V₁ to V₂ in three different ways. The work done by the gas is W₁ if the process is purely isothermal, W₂, if the process is purely adiabatic and W₃ if the process is purely isobaric. Then, choose the correct option.

Options

• W₁ < W₂ < W₃

• W₂ < W₃ < W₁

• W₃ < W₁ < W₂

• W₂ < W₁ < W₃

Answer 1

W₂ < W₁ < W₃

Explanation:

When we look at the area under the given figure, we get:

A₃ > A₁ > A₂

Hence, W₃ > W₁ > W₂
