1. The problem statement, all variables and given/known data Temperature of a gas (in kelvin) is proportional to the average kinetic temperature of its particles. Question: The temperature of 55k (277C) to 1100k(827C). At 277C the mean kinetic energy of the gas is 1.14x10^20. What is it at 827C? 2. Relevant equations kinetic energy= ½ x mass x (velocity)² 3. The attempt at a solution 55k to 1100k is x20. 1.14x10^20 x20=2.28x10^21. Just wanna check this is correct as I have an exam tormorrow.
