A liquid.
A liquid takes the shape of its container.
Due to the constant motion of the particles in a liquid, the particles could theoretically keep moving so that the liquid never takes a form. But putting the liquid into a container effectively throws a huge wall in front of the moving particles that they cannot get past. the particles hit the sides of the container and change direction. The liquid then remains in that shape despite the fact that its particles are still moving (hitting the sides of the container). Because a liquid has stronger intermolecular forces than gases, the liquid stays in liquid form and does not just evaporate once it is put into a container and its particles hit an obstacle.

Gas will always keep expanding until it fills the entire shape and volume of whatever container you put it in. Liquid won't do that. It just lays there in the bottom. It takes the shape of the container, but keeps the same volume it had when you poured it in there.
No. the density is a characteristic of the liquid itself and not dependant on the container holding the liquid. Think of it this way: would the boiling point of a liquid change with the shape of a container? Another thought: think of a very rich, dense chocolate cake, as opposed to a very light angel food cake. You can have a very thin slice of the chocolate cake, or a ridiculously decadent slab. both pieces have the same quality of denseness, even if one is much more fun to eat.
The volume of a sample of liquid is fixed, but may expand or contract with heat. The shape of a liquid is defined by its container. In the absence of gravity, liquids outside a container will assume a generally spherical shape.

The state of matter that has definite volume, but indefinite shape is the liquid state. A solid constantly has the same shape and volume. A wooden block (solid) will not change its shape or volume unless it is melted, but that would involve changing it from solid to liquid. A liquid constantly has the same volume, but its shape changes. Find a cylindrical container that has the same volume as a rectangular container. Fill the cylindrical container with water. Then, pour the water to the rectangular container. The shape of the water changed from cylindrical to rectangular and the volume remained the same, unless some water was dropped in the process. A gas has changing shape and volume. Find a small container full of a colored gas. Open in it inside a room. The gas will spread all over the room. Its volume changed from the volume of the container to the size of the room. Its shape has changed from the shape of the container to the shape of the room.
