A gas is filled in a cylinder. its temperature is increased by 20% on the Kelvin scale and volume is reduced by 10% How much percentage of the gas has to leak for pressure to remind constant ?

A

0.3

B

0.4

C

0.15

D

0.25

Text Solution

Verified by Experts

The correct Answer is:
D
According to Charlie.s law
`VpropT` (P= constant)
`rArrV/T=(V.)/(T.)rArrV.=1.2V`
Volume is reduced by 10% `rArrV.=0.9V`
% of volume leaked out
`=((1.2-0.9)V)/(1.2V)xx100=25%`
