NEET Physics Kinetic Theory of Gases Questions Solved


Pressure versus temperature graph of an ideal gas at constant volume V of an ideal gas is shown by the straight line A. Now mass of the gas is doubled and the volume is halved, then the corresponding pressure versus temperature graph will be shown by the line

1. A                           

2. B

3. C                         

 4. None of these

2.  P=μRTV=mRTMV        μ=mM  So, at constant volume pressure-versus temperature graph is a

     straight line passing through origin with slope mRMV . As the mass is doubled and volume is halved

     slope becomes four times. Therefore, pressure versus temperature graph will be shown by the line B.
