What are the characteristics of gaseous state?

Characteristics of gases.

• Gases have neither definite shape nor definite volume.
• They have lower density than liquids and solids.
• They are highly compressible.
• Gases intermix completely in all proportion without any mechanical aid.
• They exert pressure equally in all direction.

Why are gases less dense?

This is because the particles are tightly packed in both states. The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense.

What is low density of gas?

Gases usually tend to have a low density mainly because the intermolecular force of attraction better the gas molecules is very low. In gases, they have the least Mass / Volume. Thus, the increased volume mostly accounts for the low density of gases.

What is gaseous state?

the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throughout any container.

What are the properties of a gaseous state?

The gaseous state features very small attractive forces between the gas particles, which are separated from each other by relatively greater distances when compared to liquids and solids. It is important to note that substances that exist in the gaseous state do not have any definite volume or any definite shape.

Is there such a thing as an ideal gas?

While a real gas has negligible inter-molecular forces of attraction, an ideal gas has zero inter-molecular forces of attraction because the molecules of an ideal gas move so fast, and they are so far away from each other that they do not interact at all. There is no ideal gas that exists naturally.

What are the properties of a gas Gage?

Some of the important properties of gages are : 1. A gas has no definite shape or volume of its own. It acquires the shape of the container. Reason: Intermolecular attraction is the weakest in gases whereas intermolecular separation is the largest.

What are the names of the pure gases?

These are Helium, Neon, Argon, Krypton, Xenon, Radon, Hydrogen, Nitrogen, Oxygen, Fluorine and Chlorine. These gases are called pure gases. The difference in the intermolecular distances between the particles of solids, liquids, and gases are illustrated below.
