In order to increase the volume of a gas by 10%, the pressure of the gas should be `:`

Options

A. decreased by `10%`
B. increased by `1%`
C. increased by `10%`
D. increased by `1%`

Answer

D

Explanation

According to Boyle 's law Pressure is inversely proportional to volume. or PV = constant
`thereforeP_(1)V_(1)=P_(2)V_(2)`
`P_(2)=(PxxV^(2))/(1.1V)`
`p_(2)=0.9xxp(i.e.,10%` decrease in pressure).
