properties of solid , liquid and gases
Answers
Answer:
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Answer:
Explanation:
Solids
In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
Most solids are hard, but some (like waxes) are relatively soft. Many solids composed of ions can also be quite brittle.
Crystalline Arrangement of Quartz crystal cluster. Some large crystals look the way they do because of the regular arrangement of atoms (ions) in their crystal structure.
Solids usually have their constituent particles arranged in a regular, three-dimensional array of alternating positive and negative ions called a crystal. The effect of this regular arrangement of particles is sometimes visible macroscopically .
Some solids, especially those composed of large molecules, cannot easily organize their particles in such regular crystals and exist as amorphous (literally, “without form”) solids.
Glass is one example of an amorphous solid.
Liquids
If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact.
This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume.
However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Gases
If the particles of a substance have enough energy to completely overcome intermolecular interactions, then the particles can separate from each other and move about randomly in space.
Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either.
