The Difference Between Hot Cold Molecules Sciencing

Apr 24, 2017Differences in molecular movement. Temperature is a measure of energy. The higher the energy, the higher the temperature. The energy absorbed by the molecules on a body make the molecules of the body agitate and move faster, in a chaotic way. Colder bodies have molecules that move slower with less chaos. Molecules in a solid can not move freely but they agitate faster.
