Homework Statement
What is the ratio of the average speed of an atom of neon to another atom of neon at twice the temperature?
(A) 1:1
(B) 1:1.4
(C) 1:2
(D) 1:4
Homework Equations
KE = 3/2RT
The Attempt at a Solution
I used the above equation and substituted 2 for T for twice the temperature and 1 for half of that:
KE=3/2RT = 3R
KE=3/2RT = 3/2R
My ratio is 3:1.5. The correct answer is B. So kinetic energy is proportional to temperature, but what is the relationship between speed and kinetic energy?
