Question

The ratio of adiabatic bulk modulus and isothermal bulk modulus of gas is `("where"  γ = "C"_"P"/"C"_"V")`

Options

  • 1

  • γ

  • `γ/(γ - 1)`

  • `(γ - 1)/γ`

MCQ

Solution

γ

Explanation:

Adiabatic bulk modulus (Ka) = γP

Isothermal bulk modulus (K1) = P

∴ `"K"_"a"/"K"_1 = (γ"P")/"P" = γ`
