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 ...

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

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 ...

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 ...

Prior research has shown that the strength of the heliospheric magnetic field rises and falls over a predictable 11-year cycle, exerting a variable force on the charged particles that are moving ...

Earlier this week we broke down the complexities of mixed-phase precipitation forecasting.Within that we briefly touched on a key component to that complexity w ...

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 ...
