32 g of O_2 is contained in a cubical container of side 1 m and
maintained at a temperature of 127ºC. The isothermal bulk modulus of
elasticity of the gas in terms of universal gas constant R is

Show answer and solution

Bulk modulus of elasticity at constant temperature

B = \frac{dP}{dV/V} - = - V\left( \frac{dP}{dV} \right)_{T} = + P = \frac{nRT}{v}

= \frac{1 \times R \times 400}{1^{3}} = 400R
