One mole of an ideal gas expands adiabatically at constant pressure such that its temperature T 1 V . The value of for the gas is ( = C_p C_v , V= . Volumeof thegas )

Options

  1. A1.8
  2. B1.5
  3. C1.3
  4. D1.4

Correct answer

B. 1.5

Step-by-step solution

For an adiabatic process at constant pressure, we have TV ^ -1 = constant Given, TV ^ 1 / 2 = constant Hence, -1= 1 2 or =1.5
