Question

To what temperature must a gas sample initally at 13 degrees be raised in order for the avarage energy of its molecules to double?

Answer 1

in general, temperature is related to the average energy (vibration, movement) of molecules. Double the temperature, you double the energy. http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/kintem.html

so if you were at 13C, or 286K, double that to double average energy. Ans: 576K, or 299C
