A certain gas is taken to the five s t a t e s represented by dots in the graph. The plotted lines are isotherms. Order of the most probable speed (v_p ) of the molecules at these five states is

Options

  1. A(v_ p at 3 >v_ p at 1 =v_ p at 2 >v_ p at 4 =v_p ) at 5
  2. B(v_ p at 1 >v_ p at 2 =v_ p at 3 >v_ p at 4 =v_p ) at 5
  3. C(v_ p at 3 >v_ p at 2 =v_ p at 4 >v_ p at 1 =v_ p at 5 )
  4. Dinsufficient information to predict the result.

Correct answer

A. (v_ p at 3 >v_ p at 1 =v_ p at 2 >v_ p at 4 =v_p ) at 5

Step-by-step solution

Stages 1 and 2 are at the same temperature. Also stages 4 and 5 are at same temperature. As V_p is more at higher temperature and same at all stages at equal temperature. V_ P₃ >V_ P₁ =V_ P₂ >V_ P₄ =V_ P₅ .
