1. The problem statement, all variables and given/known data A stationary gas has a kinetic energy of 500 J at 30 C. What is its kinetic energy at 60 C? 2. Relevant equations KE = 3/2 RT 3. The attempt at a solution I first converted T to Kelvin = 333K. I substituted all the values in to find KE but my answer is around 40K, which is not even close to the right answer. KE = 3/2RT = 3/2 * 0.08*333 = 40 K. What am I doing wrong?
