condensing and other changes of state can also be understood using this simple model. If the particles are heated up, they gain energy and can move more freely, changing from a solid to a liquid ...

Once again, the particles in a gas hit the walls of the container more often, causing the pressure to rise. Most substances can exist as a solid, liquid or gas. They can change state, usually when ...

The particles can now move from their fixed positions, and the substance changes state. First from solid to liquid, then if we continue heating to raise the temperature and break the remaining ...

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

Flows involving solid particles are used extensively in the chemical process industries, including areas such as petrochemicals, pollution control, powder technology, coal combustion, and ...

Dissolving happens when the attraction between the particles of the solvent and solute ... It changes from water (liquid) to ice (solid). Explain that another change in state is when liquid water ...
