Homework Statement


A container has neon gas in the temperature 273 K. We heat the container to the temperature 373 k, keeping the volume constant. Find the average velocity of the molecules of neon before and after the heat.

Homework Equations



U=3/2vRT

The Attempt at a Solution


I thought to us the formula U=3/2vRT but I don't have delta U.

ΔU = ΔQ + ΔW, since no work was done by/to the system then ΔW = 0, and you're left with ΔU = ΔQ !
Hope this help :) !!

Energy (U) is proportional to temperature (T). How do you relative speed (v) and temperature (T)? Hint: What form of energy do the molecules possess?
