When temperature of a gas is `20^@C` and pressure is changed from `p_(1)= 1.01 xx 10^(5) Pa` to `p_(2) = 1.165 xx 10^(5) Pa`, the volume changes by `10%`. The bulk modulus is
A. `1.55xx10^(5)Pa`
B. `0.115xx10^(5)Pa`
C. `1.4xx10^(5)Pa`
D. `1.01xx10^(5)Pa`

Correct Answer - A
`B=(/_P)/(/_v//V)=((1.165xx10^(5)-1.01xx10^(5)))/0.1`
`=1.55xx10^(5)Pa`
