The average translational kinetic energy...

The average translational kinetic energy of air molecules is `0.040 eV (1eV=1.6xx10^(-19)J).` Calculate the temperature of the air.
Boltzmann constant `K=1.38xx10^(-23) J K^(-1).`

Text Solution

Verified by Experts

`K = (3)/(2)k T`
`0.04 xx 1.6 xx 10^(-19) = (3)/(2) xx 1.38 xx 10^(-23)T`
`T = 309 K`
