Temperature T and Energy 1. The hotter an object is, the faster its atoms move.

Temperature T and Energy 1. The hotter an object is, the faster its atoms move. The atoms have a lot of kinetic energy KE. KE is motion energy. High T ? atoms move fast ? more KE Low T ? atoms move slow ? less KE 2. The lowest possible T is absolute zero.
