Under isothermal condition, the pressure of a gas is given by P = a V – 3 , where a is a constant and V is the volume of the gas. The bulk modulus at constant temperature is equal to
Options
- A3 P
- BP
- C2 P
- DP 2
Correct answer
A. 3 P
Step-by-step solution
The data given is P = a V - 3 Bulk modulus is given by, B = - d P d V V = - V d P d V = - V d d V a V 3 = - V - 3 a V 4 = 3 a V 3 = 3 P
