32 g of O 2 is contained in a cubical container of side 1 m and maintained at a temperature of 127 ° C . The isothermal bulk modulus of elasticity of the gas is (universal gas constant = R )

Options

  1. A127   R
  2. B400   R
  3. C200   R
  4. D560   R

Correct answer

B. 400   R

Step-by-step solution

The bulk modulus of elasticity at a constant temperature P V = n R T d P P = d V V B =   - d P d V / V B = P B = n R T V =   R 400 1 3 = 400 R
