In order to double the average energy of the molecules in a gas at 200 K,?

Question

its temperature must be changed to which of the following?

A. 800 K
B. 100 K
C. 400 K
D. 1600 K

Answer 1

Energy of the molecules = 3/2*nRT

if you want the energy to be double, then the temperature must be : energy = 3/2*nR*(2T)

if initial temperature was = 200 K

final temperature was = 400 K

Hope that helped
