At any temperature, the particles (atoms and molecules) of a substance, in this case a gas, move at different speeds. If energy is added by heating, the particles move faster. If energy is removed by ...

Substances can exist in three states of matter ... move with random motion throughout the container. In gases the particles move rapidly in all directions, frequently colliding with each other ...

liquid and gas] In the solid state the particles of the substance are packed tightly in fixed positions and are all touching. The particles move about a fixed position; they vibrate. In the liquid ...

This research is part of a growing field called ‘active matter,’ which could one day lead to new drug delivery methods and ...

In quantum physics, subatomic particles behave strangely—they can be in two places simultaneously, move through solid objects ...

Powering this event was some mysterious substance in the universe ... so it's worth searching for these odd particles. We've been trying to move past the Standard Model of particle physics ...

Micro- and nanoscale plastic particles in soil and water can significantly increase how much toxic chemicals plants and human intestinal cells absorb, according to two new studies from Rutgers Health ...

Eventually, the particles are spread through the whole liquid or whole container. Diffusion happens on its own, without stirring, shaking or wafting. In living things, substances move in and out ...
