Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume The change from solid to liquid usually does not significantly change the volume of a substance. A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving It takes the shape of its container but maintains constant volume. Gas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states The remarkable feature of gases is that they appear to have no structure at all
They have neither a definite size nor shape, whereas ordinary solids have both a definite size Gas has no definite volume and shape Gases are the only state of matter with no definite shape or volume In contrast, solids have a definite shape and volume, while liquids only have a definite volume and take the shape of their container. Liquid is a physical form of matter that has a definite volume, but no definite shape A solid has a definite volume and a definite shape and a gas has no definite volume or shape.
Most solids are hard, but some (like waxes) are relatively soft Many solids composed of ions can also be quite brittle Solids are defined by the following characteristics: Atoms, ions, or molecules make up all matter These particles can move in different ways In some matter, they are close together and vibrate back and forth
In other matter, the particles are farther apart Sometimes, they slide past each other At other times, they move freely and spread out. Gases change in both shape and volume Gas is the state of matter that has no definite shape or volume.
