Gas Characteristics
1. Gasses expand to fill the container they are in..
2. Gasses are fluids in the fact like liquids they can flow form one place to another.
3. Gasses have low density in that the individual gas molecules are far apart.
4. Gas molecules can be compressed thus changing their densities..
5. Gas molecules freely and evenly intermix as they spread into each other, much like perfume will spread through a room from its source (diffusion) or gas will flow rapidly from high pressure to low pressure through a small opening (effusion).
