Four characteristics properties of gases
Answers
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.
Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid state
Indefinite Shape or Volume. Gases have no definite shape or volume.
Compressibility and Expandability.
Diffusivity.
Pressure.
