It is usually called the capacity. It is basically the same thing as the volume.
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.
Crystals of a certain mineral have a regular formation of atoms. However, crystals of the same mineral can grow differently. The presence of trace minerals, variations in heat, pressure, and the space that they have to grow in can influence the shape of a crystal. Crystalline structures demonstrate characteristic geographic variations for these reasons.
take up space and have particles
There are many possible science projects dealing with insulation. For example, build several small containers with each wrapped in a different insulating material, then put an icecube (all the same size!) in each container, and see how the time needed for the icecube to melt varies depending upon the type of insulation used. Or put a small light bulb in each container (all of the same wattage!) and then measure the resulting temperature in each container after ten minutes. Or make blankets of various different insulating materials and see which one keeps you warm at night the most effectively.

Gas expands to fill up it's container, while if solids are put into the same container, the will not expand. They will stay the same size and shape.
Gas has the same shape as its container fills. But some gases are visible.
Capacity is the same as the volume of the inside of a container. Often, in mathematical exercises, the internal and external volumes are assumed to be the same (ie thickness of the container is zero). In this case, the capacity is the same as the internal or external volume.
yes because if the container is smaller it has a greater pressure than a bigger container. ;)
the same shape
A liquid takes the shape of its container.
shape but not the volume
liquids
volumen
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.
