WebWhen heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space. WebApr 7, 2024 · It's both: At the smallest scale, thermal energy is just kinetic energy, the energy of motion.That is, thermal energy (heating up) and kinetic energy are the same thing. When molecules vibrate, they're bumping into each other—transferring kinetic energy to other molecules, which sometimes radiate this energy as heat (on a larger scale). macl internetWebMar 8, 2024 · The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products.
