The bulk modulus of a gas is defined as ...

The bulk modulus of a gas is defined as B = -VdP/dV. For an adiabatic process the variation of B is proportional to `P^(n)`. For an idea gas, n is

A

0

B

1

C

`5/2`

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
For adiabatic process `P V^(gamma)` = C
`gamma PV^(gamma-1)+(dP)/(dV)V^(gamma) =0 implies Pgamma = -V (dP)/(dV)`
Hence n = 1
