Thermodynamic process is shown below on a P - V diagram for one mole of an ideal gas. If V 2 = 2 V 1 , then the ratio of temperature T 2 T 1 is :

Options

  1. A2
  2. B1 2
  3. C1 2
  4. D2

Correct answer

A. 2

Step-by-step solution

P V 1 / 2 = c n R T V V 1 / 2 = c T = c 1   V 1 / 2 T 2   T 1 = V 2   V 1 1 / 2 = 2   V 1   V 1 1 / 2 T 2   T 1 = 2
