What are the characteristics of a gas?

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. An internal combustion engine provides a good example of the ease with which gases can be compressed.

So, what are the similarities between a liquid and a gas?

Sold, liquid, and gas all have volume and shape. They are all made up of atoms, molecules, or ions. Liquids and solids can be referred to as condensed phased because their particles are close together. Liquids and gases flow easily because their particles can move or slide past one another.

What does a solid and a gas have in common?

Solid, liquid, and gas are common states of matter. A substance can exist as a solid, a liquid, or a gas. The state of a substance depends on the space between its particles and on the way in which the particles move. The particles in all matter are always in motion.

What are 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.
