Question

When temperature of a gas is `20^@C` and pressure is changed from `p_1=1.01xx10^5Pa` to `p_2=1.165xx10^5Pa` then the volume changed by `10%`. The bulk modulus is
A. `1.55xx10^5Pa`
B. `205xx10^5Pa`
C. `107.4xx10^5Pa`
D. `53.7xx10^5Pa`

Answer 1

Correct Answer - A
`B=(dP)/((dV)/(V))=((1.165-1.01)xx10^5)/((10)/(100))Pa`
`=1.55xx10^5Pa`
