NEET Physics Kinetic Theory of Gases Questions Solved


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

1. 30%                           

2. 40%

3. 15%                           

4. 25%

4.    Let initial conditions = V. T        and final conditions =V'.T'        By Charle's law VT  P remains constant        VT=V'T'  VT=V'1.2 T'  V'=1.2 V         But as per question, volume is reduced by 10% means V=0.9 V         So percentage of volume leaked out =1.2-0.9 V1.2 V×100 =25%
