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 ...

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 ...

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 ...

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

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 ...
