Kinetic theory of gases is a generalization offered by Maxwell. Boltzmann, Clausius, etc. to explain the behaviour of ideal gases. This theory assumes that ideal gas molecules neither attract nor repel each other. Average kinetic energy of gas molecules is directly proportional to the absolute temperature. A gas equation called kinetic gas equation was derived on the basis of kinetic theory
`PV = (1)/(3) mv^(2)`
The kinetic energy of 2.8 g of nitogen gas at `127^(@)C` is nearly :
A. `2 xx 249.3 J`
B. `2 xx 200.4 J`
C. `2 xx 2.5 J`
D. `20.5 J xx 2`
