The gases carbon-monoxide (CO) and nitrogen at the same temperature have kinetic energies `E_(1)` and `E_(2)` respectively. Then

Options

A. `E_(1)=E_(2)`
B. `E_(1)gtE_(2)`
C. `E_(1)ltE_(2)`
D. `E_(1) and E_(2)` cannot be compared

Answer

A

Explanation

Both carbon monoxide (CO) and nitrogen `(N_(2))` are diatomic. Hence they have equal K.E. Both of them have 5 degrees of freedom and each one has
`K.E. =5(1/2kT)=5/2kT" "thereforeE_(1)=E_(2)`
