Question
A gas is filled in a cylinder, its temperature is increased by 20% on kelvin scale and volume is reduced by 10%. How much percentage of the gas will leak out at constant pressure :-
Options
A.30%
B.40%
C.15%
D.25%
Solution
Let initial conditions = V,T
and final conditions = V′,T′
By Charle′s law V ∝ T [P remains constant]
⇒ V′ = 1.2 V
But as per question, volume is reduced by 10% means V′ = 0.9 V
So percentage of volume leaked out
=
× 100 = 25%
and final conditions = V′,T′
By Charle′s law V ∝ T [P remains constant]
⇒ V′ = 1.2 VBut as per question, volume is reduced by 10% means V′ = 0.9 V
So percentage of volume leaked out
=
× 100 = 25%Create a free account to view solution
