Hi
Qoutation:
"Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving.
When 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.
Mass of the object remains the same, however. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed."
I am just wondering: If matter loses heat, it loses photons (because heat is made up of photons). But if it is loosing energy, how come it isn't losing mass? What happened to E=mc2, where energy is a form of mass?
Electrons lose energy because of the resistence in different materials. This energy comes out as heat. Why would matter not lose mass when losing heat (energy)?PS. The name of the website is https://www.mansfieldct.org/Schools/MMS/staff/hand/atomsheat.htm
