Does gas keep its shape like a solid? Can you pour gas like a liquid?
Answer (1)
In physics, the properties of gases are quite different from those of solids and liquids.
Shape and Volume:
Solids have a definite shape and volume, meaning they maintain their shape regardless of the container they're in.
Liquids have a definite volume but take the shape of the container they are in.
Gases do not have a definite shape or volume. Instead, they expand to fill the entire volume and shape of their container.
Pouring:
While you can pour liquids because they flow to take the shape of the part of the container they occupy, gases behave slightly differently. You don't 'pour' gas like a liquid. Instead, gases will spread out and fill any available space they can reach, moving from areas of higher concentration to areas of lower concentration.
So, to answer your questions:
No, gas does not keep its shape like a solid. It will always expand to fill the shape of its container.
While you don't pour gas in the same way as a liquid, gases can be transferred between containers, often using tubing or other indirect methods.
