Question

The isothermal bulk modulus of a gas at atmospheric pressure is:

• A. $2.026\times {10}^{5}N/m^2$
• B. $1.013\times {10}^{5}N/m^2$
• C. $1mm$ of $Hg$
• D. $13.6mm$ of $Hg$

Answer 1

Answer: (B)

The isothermal bulk modulus of a gas is equal to the atmospheric pressure i.e., $1.013\times {10}^{5}N/m^2$
