Gaseous state of matter

Answer 1

A gas is a compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container.

In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small, and the typical distance between neighboring molecules is much greater than the molecular size. A gas has no definite shape or volume, but occupies the entire container in which it is confined.

Answer 2

As mollecules change their arrangements at certain conditions, and change their properties accordingly, matter is divided into seperate forms. At a solid form, atoms are tightly packed together and incapable of movement, until they reach the right temperature, hotter than their current one. At that temperature, their attoms begin to move about, and the atoms are capable of sliding past one another; a state known as liguid. When a liquid is heated even more, the atoms move much faster and are capable of moving freely, and the overall material becomes less dense, so it can often move through the air, in a form of matter known as a gas.

The best way to visualize these changes would to get hold of an ice cube. After it heats up enough, the bonds become looser, and it becomes a liquid; water. Now, if you heat the water, boiling it would be the most effecient way, it starts to evaporate, and turn into water vapor.

Answer 3

The gaseous state of matter is characterized by particles that are far apart, move freely and have high kinetic energy. Gases have no fixed shape or volume, and they expand to fill the entire container in which they are placed. Examples of gases include oxygen, nitrogen, and carbon dioxide.
