  • question_answer
    In an ideal gas at temperature T, the average force that a molecule applies on the walls of a closed container depends on T as \[{{T}^{q}}.\] A good estimate for q is : JEE Main Online Paper (Held On 10 April 2015)

    A)  1                                            

    B) \[\frac{1}{4}\]

    C) \[\frac{1}{2}\]                                   

    D)  2

    Correct Answer: A

    Solution :

                    \[F=\frac{2mv}{t}\]\[t=\frac{2l}{v}=\frac{\text{distance}}{\text{velocity}}\] \[t\propto \frac{1}{v}\]                                 \[F\propto {{v}^{2}}\] and \[K.E.\propto T\]                     \[\frac{1}{2}m{{v}^{2}}\propto T\] \[{{V}^{2}}\propto T\]                   \[\Rightarrow \] \[F\propto T\]
