प्रश्न

At what temperature will average kinetic energy of gas be exactly half of its value at N.T.P.?

उत्तर

Solution:
Kinetic energy of gas = `3/2RT`

K.E `prop` T

`(K.E)_2/(K.E)_1=T_2/T_1`

`1/2=T_2/273`

`T_2=136.5K`

At 136.5 K, the average kinetic energy of the gas will be exactly half of its value at N.T.P.
