i am working on trying to derive KE (or Etrans)=3/2nRT
so i know these steps
and pV= 1/3 NmV2
and combining them, we get
also, we know that for translational motion, KE= 1/2Nmv2
i don't know how
2/3 (1 /2 Nmv2) = nRT
where did that 2/3 come from??!!
i know that subsequently, it will be 2/3KE= nrt
and i will get KE=3/2 nRT
i just don't KNOW WHERE THE 2/3 came from in the first place!
