Choose the correct statement for processes A & B shown in figure.

Options

  1. AP V γ = k for process B and P V = k for process A .
  2. BP V = k for process B and A .
  3. CP γ - 1 T γ = k for process B and T = k for process A .
  4. DT γ P γ - 1 = k for process A and P V = k for process B .

Correct answer

A. P V γ = k for process B and P V = k for process A .

Step-by-step solution

Steeper curve (B) is adiabatic For adiabatic ⇒ PV γ = constant and curve (A) is isothermal. Therefore, T = constant ⇒ P V = constant
