Why do gases fill the liquids containers?

Answer 1

Gravity.

The gravitational pull of the Earth will exert a force on anything with a mass and pull it towards the centre of the Earth. As we're essentially standing on the surface of a sphere, the centre of the Earth is pretty much straight down and gravity will pull liquids to the bottom of any container.

Answer 2

Liquid is one of the three classical states of matter. Like a gas, a liquid is able to flow and take the shape of a container, but, like a solid, it resists compression. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena. The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter.

On the other hand, as liquids and gases share the ability to flow, they are both called fluids. Liquid is one of the three primary states of matter, with the others being solid and gas. A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid, allowing a liquid to flow while a solid remains rigid.

Answer 3

That's because the forces between the atoms are such that 1) they are free to flow, and 2) they keep their volume (approximately, at least). Also, gravity pulls them down.

Answer 4

Liquids have fixed volume but not a fixed shape; they can flow to fill a container.

Answer 5

In a nonhomogeneous mixture this is the denser liquid.

Answer 6

This is an effect of gravity.

Answer 7

Gravity.

The gravitational pull of the Earth will exert a force on anything with a mass and pull it towards the centre of the Earth. As we're essentially standing on the surface of a sphere, the centre of the Earth is pretty much straight down and gravity will pull liquids to the bottom of any container.
