Q. To double the translational kinetic energy of the molecules of a gas one has to
AMU
AMU 1997
A
double the absolute temperature
B
reduce the absolute temperature to half
C
increase the absolute temperature fourfold
D
increase the absolute temperature by a factor of $ \sqrt{2} $
Solution:
: The mean kinetic energy of translation $ =\frac{3R}{2}T $ $ {{E}_{K}}\propto T $ Hence to double $ {{E}_{K}}, $ absolute temperature T be double.
