See if this makes sense - http://en.wikipedia.org/wiki/Kinetic_theory#Temperature_and_kinetic_energy

anonymous · Answer

i tried looking at that before i asked. I dont think i understand like any of it, to be honest. please help cx @LastDayWork

lastdaywork · Answer

Use - 
PV = NRT
PV = (2/3)K
K = (1/2)mv^2

BTW what is "cx" ??

anonymous · Answer

You should use Maxwell-Boltzmann velocity distribution..

anonymous · Answer

$$v _{average} =\sqrt{\frac{ 8RT }{ \pi M }}$$
