Isothermal bulk modulus of a gas at a pressure $\mathrm{P}$ is ( $\gamma$ - ratio of specific heat capacities of the gas)
  1. $\gamma$
  2. $\gamma \mathrm{P}$
  3. $\mathrm{P}$
  4. $\frac{\gamma}{P}$

Solution

Isothermal bulk modulus of a gas $\mathrm{B}_{\text {Isothermal }}$ $=-\frac{\Delta \mathrm{P}}{\frac{\Delta \mathrm{V}}{\mathrm{v}}}=\mathrm{P}$
