The volume vs. temperature graph of I mole of an ideal gas is given below. The pressure of the gas (in atm) at X, Y and Z , respectively, are

Options

  1. A0.328,0.820,0.820
  2. B3.28,8.20,3.28
  3. C0.238, 0.280,0.280
  4. D32.8,0.280,82.0

Correct answer

A. 0.328,0.820,0.820

Step-by-step solution

Using ideal gas equation, PV = nRT array l P = nRT V ; P _ x = 1 0.082 200 50 =0.328 ~atm P _ y = 1 0.082 500 50 =0.820 ~atm P _ x = 1 0.082 200 50 =0.820 ~atm array
