Gaseous Coagulate
and Expansive Tendencies
Taking up the room
Gases are also fluids just like liquids. However Gases have the unique property that they will take up the room that they occupy. Gases are really good at spreading out evenly and that is there natural behavior. This is how we are able to have oxygen almost everywere because the gas fills up all the space which allows us to breath in the air, which our lungs then filter out the oxygen.
NOTE: Clouds are not actually Gas however since water vapor is invisible clouds are the best physical depiction of this phase.
Vacuum
Vacuums are the absence of gases. This takes a strong container and a very strong pump. The reason why is because even though gas doesn't feel like it has weight, it does. This weight is what allows our bodies to stick together and helps nature. The reason why Vacuums need strong containers is because all the gases around them are putting a ton of pressure against them trying to fill that space.
