The slopes of the isothermal and adiabatic p-V graphs of a gas are by S_I and S_A respectively. If the heat capacity ratio of the gas is 3 2 , then S_I S_A =

Options

  1. A3 2
  2. B2 3
  3. C1 2
  4. D1 3

Correct answer

B. 2 3

Step-by-step solution

The slope of isothermal (S_I ) and adiabatic (S_A )p-V graph of gas are related as Slope of adiabatic = slope of isothermal S_A= S_I S_I / S_A=1 / = 1 3 / 2 ( . Given . = 3 2 )=2 / 3
