So can sound, almost as if anything with energy can move or excite particles.
In other news scientist discovers water is wet.
- viraptor 3y agoSound would literally mean waves of kinetic energy hitting both the surface of the water and traveling inside it. Does that really count as "without heat"?
- Sparkyte 3y agoAnd what type of energy is light?
- viraptor 3y agoOne which can get absorbed by a single molecule individually as opposed to sound which has to affect large groups of them, increasing movement / heat.
- MagicMoonlight 3y agoSound is movement, it’s not a particle. It’s your way of sensing stuff smashing together by feeling the ripple that comes off it
- Sparkyte 3y agoBoth kinetic energy.
- bmacho 3y agoImagine a material, or a passive device, that can evaporate a glass of water fast, using only the heat of the environment, as the energy source. That is possible, and would be huge.
- mrguyorama 3y agoIt would not be. If you do not replace the "heat" absorbed by the evaporating water, the room cools down. The kinetic energy needed to maintain water molecules as a gas instead of condensing comes from somewhere. This is a very complicated swamp cooler.
