1. The problem statement, all variables and given/known data 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? 2. Relevant equations KE = 3/2 RT; v1/v2 = sqrt. m2/sqrt. m1 3. 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?
