A gas is one of the four fundamental states of matter (solid, liquid, gas, and plasma). genui{"chemistry_atoms_molecules_matter_learning_block_staging":{"type_id":"STATES_OF_MATTER_PARTICLE_MODEL"}} Definition A gas is a state of matter in which the particles (atoms or molecules) are far apart, move freely in all directions, and have neither a fixed shape nor a fixed volume. A gas expands to completely fill any container in which it is placed. Key Characteristics of Gases Property Description Shape No fixed shape; takes the shape of its container Volume No fixed volume; expands to fill the entire container Particle Arrangement Particles are widely spaced Particle Motion Rapid, random motion in all directions Compressibility Highly compressible due to large spaces between particles Density Generally much lower than solids and liquids Diffusion Mixes quickly with other gases Fluidity Flows easily Examples of Gases Oxygen (O₂) Nitrogen (N₂) Hydrogen (H₂)...
