What is the ratio of the average speed of an atom of neon to another atom of neon at twice the temperature but the same pressure?
KE = 3/2 RT; v1/v2 = sqrt. m2/sqrt. m1
The Attempt at a Solution
I first used KE = 3/2RT and substituted 1 and 2 for T and set them equal to each other. I ended up with a ratio of 1:2. Why is the answer 1:1.4?
