A gas follows a process `TV^(n-1)=const ant`, where `T=` absolute temperature of the gas and `V=` volume of the gas. The bulk modulus of the gas in the process is given by

Options

A. (a) `(n-1)p`
B. (b) `p//(n-1)`
C. (c) `np`
D. (d) `p//n`

Answer

C

Explanation

`TV^(n-1)=` constant
`:.` `(pV)V^(n-1)=` constant (as `TproppV`)
`:.` `pV^n=` constant
Bulk modulus in the process `pV^gamma=` constant is `gammap`. Hence, in the given process Bulk modulus is np.
