What is the average translational kinetic energy of a nitrogen molecule at stp?

35meV

Explanation:

To find the average translational kinetic energy you use the followinf formula:

K_B: Boltzman' constant = 1.38*10^-23 J/K

T: standard temperature = 273.15K

By replacing these values you obtain:

in eV you have:

5.65*10^-12(6.242*10^18eV)=0.035eV=35meV

Hence, the average translational energy is 35meV

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
