States of Matter - Labster Theory - hth华体会最新网站

On earth, we commonly find three states of matter:solid,liquid, andgas.

The molecules of water move differently depending on the state of matter. In the gas form they move freely, in the liquid form they have a more restricted range of movement, and in the solid form they are not changing positions, but vibrating in place

Figure 1.Three states of water molecules.

Solidis rigid; it has both a fixed shape and volume.
Liquidassumes the shape of its container; it has a distinct volume but has no specific forms.
Gas, also known as vapor, takes the volume and shape of its container; it has no definite shape and volume.

The molecular arrangement of the molecules in the substance determines the different properties of solid, liquid, and gas.

In some high-temperature environments (for example the interior of stars, TV screens, or lightning strikes), we could find another state of matter calledplasma. Plasma is a gaseous state of matter that contains a number of electrically charged particles.
