PHYSICAL PROPERTIES OF GASES A gas can be compressed to a smaller volume resulting in an increase in density. This is why air is used as a shock absorber in the form of air bags installed in cars.

Gas particles are far apart and always moving. Gases behave differently from solids and liquids.

One. Kinetic energy - Gas particles have high kinetic energy, moving freely and rapidly in all directions.

Two. Shape and volume - Gases do not have a fixed shape or volume; they expand to fill the container.

Three. Compressibility - Gases are easily compressible because the particles are far apart.

Four. Density - Gases have low density compared to solids and liquids.

Five. Diffusion - Gas particles mix and spread out quickly due to their motion.

Six. Pressure - Gas particles exert pressure on the walls of their container due to collisions.

So basically, if a substance moves freely, spreads out, has low density, and exerts pressure, it's a gas.

Gases fill their containers uniformly. When a tire or a balloon is filled with air, the air is distributed evenly throughout the tire or balloon.

In gases, differential stress is basically negligible because:

One. Gas particles move freely in all directions.

Two. They cannot resist shape or directional forces like solids.

Three. Any applied stress is usually isotropic (same in all directions), so there's no significant difference between O one and O three.

In gases, stress is usually uniform, so "differential stress" isn't really a factor-unlike in solids or rocks.

Key behaviors:

. Expand to fill any container

. Easily compressed

. Particles move freely and randomly

. Change quickly when temperature or pressure changes

Gas exerts pressure. The pressure of the gas inside a balloon is responsible for keeping its shape.

Properties:

Two. Volume (V)

Three. Pressure (P)

Four. Amount of Gas (n)
