what are the different characteristics of gases?
26581
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

The atmospheric characteristics of rocky and gas planets differ. ... The terrestrial planets in the solar system have atmospheres made up mostly of gases such as carbon dioxide, nitrogen and oxygen. The gas giants, on the other hand, consist mainly of lighter gases like hydrogen and helium.

['It is colourless, tasteless, odourless gas.', 'It has extremely low solubility in water. Since its molecules are non-polar.', 'Its density is approximately 1/4th that of air. ... ', 'It can be liquefied at high pressures and very low temperature.', 'It is highly combustible and should be handled with care.']

Characteristics. Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.

['gas are well separated with no regular arrangement.', 'liquid are close together with no regular arrangement.', 'solid are tightly packed, usually in a regular pattern.']

4. Characteristic Properties of Matter—The Key Ideas The physical properties of matter include color, odor, density, solubility, melting point, boiling point, and electrical conductivity. These are properties that can be observed without chemically changing the substance. 5.

3) Gases – a gas has no definite shape, it takes the shape of the container that holds it. Gases are easily compressible. Molecules are separated by distances that are large compared with the size of the molecules. 4) Plasma - This state of matter makes up 99% of the visible universe.

Physical characteristics Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.

The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

The rare gases are all colorless, odorless, and tasteless. They are also monatomic gases which means that they exist as individual atoms. The most noticeable feature of the rare gases is their lack of chemical reactivity.

['A gas has no definite shape or volume of its own. ... ', 'A gas has no surface of its own. ... ', 'A gas is not rigid and is easily compressed. ... ', 'A gas can diffuse into another gas. ... ', 'A gas on cooling changes into liquid state. ... ', 'A gas can flow in all directions. ... ', 'The molecules are very loosely packed in gases.', 'Gases are not visible.']

The properties of an ideal gas are: An ideal gas consists of a large number of identical molecules. The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas. The molecules obey Newton's laws of motion, and they move in random motion.

The three major factors which affect determine the physical behavior of gases are temperature pressure and volume (T, P and V). If you notice in the above equations the factor which is held constant does not appear in the equations (use this to help remember the equations and laws).

The characteristic of a pure substance is that it only contains atoms of only one kind. It has fixed physical and chemical properties, for example, melting point, boiling point, density, solubility, etc.
