Liquids expand because their molecular structure allows them to move. Unlike solids, liquids are not constrained to one shape. That is why they can expand.

Yes, a gas will always fill the container that it is in.
The gas expand to fill the volume of the container.
Solids: they have fixed shape and fixed volume. They cannot be compressed much. They cannot flow. They do not fill their container completely. They have high density. They are heavy. Liquids: they have fixed volume but not fixed shape they take the shape of their container. They cannot be compressed much. They can flow. They do not fill their container completely. They have moderate to high density. Gases: they do not have fixed shape and volume. They can be compressed easily. They can flow. They fill their container completely. They have very low density.
A gas will expand to fill its container. This gives the gas the shape and volume of its container.
A gas will fill it's container freely, and evenly space itself throughout the container. Imagine an aerosol can of disinfectant sprayed into a room at one corner. The gas will eventually spread itself across the room evenly.
There are relatively strong forces between the particles (atoms or molecules), that keep them together.
It doesn't expand to take the shape of its container, but it flows because the particles can slide past each other, and the bonds are loose, and not completely broken, whereas in gases, the bonds between particles have been broken down, and so they can move apart and fill the container.
Gas will always fill any container that it is in, since it will expand to fill any available space. Liquid does not expand, it has a fixed volume, therefore depending upon how much liquid you pour into your container, the container may or may not be filled.

maintain their own shape and do not take the shape of their container.
Yes, a liquid does take up a definite amount of space, which is to say that it has a definite volume. A liquid takes the shape of its container but does not expand to fill it completely like a gas would.
Gas completely fills its container, liquid stays as a unit and fills the container with respect to gravity, and solids do not fill their containers
Gases do not have a fixed shape or volume; they expand to completely fill the container they occupy.
A gas. Gas will expand to fill the available space.
In a liquid, you have atoms or molecules which are bonded to each other to a sufficient degree that they stay close to each other, so they do not just expand as a gas would, to fill a container, but they are not bonded so strongly as to become a solid, so their relative positions can freely shift, resulting in a shapeless substance that takes the shape of its container.
Gases will expand to fill their containers.
