For example, liquid water turns into water vapour when it is heated enough, and it turns into ice when it is cooled enough.The closeness, arrangement and motion of the particles in a substance ...
The little spheres represent water molecules. Molecules are in constant motion. The attractions water molecules have for each other keep them close together. They can move past each other, but their ...
Fluid dynamics is the study of the motion of liquids, gases and plasmas. Flow is dependent on the intrinsic properties of the matter itself, such as compressibility, viscosity and density.
"For instance, a gas or liquid that spreads evenly to fill ... In other words, the motion of the active particles could adjust in response to the evolving porous structures, which could produce ...
