# What are the 2 properties of gas?

## What are the 2 properties of gas?

The Properties of Gases. 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.

How does the particle theory explain the properties of gases?

The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.

### What are the 4 properties of gases?

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.

What is gas particle distance?

The distance between the particles of a gas is much, much greater than the distances between the particles of a liquid or a solid. Most of the volume of a gas, therefore, is composed of the empty space between the particles.

## What are the 5 properties of gas?

What Are Five Properties of Gases?

• Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states.
• Indefinite Shape or Volume. Gases have no definite shape or volume.
• Compressibility and Expandability.
• Diffusivity.
• Pressure.

What are the 5 main ideas of particle theory?

Terms in this set (5)

• All matter is made of particles.
• Particles have space between them.
• Particles are always moving.
• Particles move faster and get farther apart when heated.
• Particles are attracted to each other.

### What are the 6 rules of particle theory?

3.2 state the postulates of the particle theory of matter (all matter is made up of particles; all particles are in constant motion; all particles of one substance are identical; temperature affects the speed at which particles move; in a gas, there are spaces between the particles; in liquids and solids, the particles …

What are the 6 properties of a gas?

What are the 6 properties of gases?

• What are the Properties of Gases? Gasses do not possess any definite volume or shape.
• Compressibility. Particles of gas have huge intermolecular spaces in the midst of them.
• Expansibility. When pressure is exerted on gas, it contracts.
• Diffusibility.
• Low Density.
• Exertion of Pressure.

## What are the 5 properties of gases?

What is the smallest gas particle?

Atom
Atom: The smallest Particle.

### What is the size of gas?

The number density of a gas was approximated to be about 1.0 × 1019 molecules per cubic centimetre, and from experiment it is known that 1 mole of gas occupies a volume of about 25 litres (2.5 × 104 cubic centimetres) under ordinary conditions.
