By what percentage should the pressure of a given mass of a gas be increased so as to decrease its volume by 10% at a constant temperature?A. 0.05B. `7.2`%C. `12.5`%D. `11.1`%

Answer» Correct Answer - D
When `T` is constant, `pV` = constant. When volume is decreased by 10% that is volume becomes `(90)/(100)`, the pressure must become `100//90`. Thus, percentage increase in pressure
`=((100-90)xx100)/(90)=11.1%`
