Particles are the unit that makes the matter. The states of matter based on particles can be solid, gas, or liquid. The matter in the experiment represents solid matter.
What are phases of matter?
The phases or states of matter are based on the composition and the distribution of the particles of the object. There are four known and observable states of matter namely solid, gas, plasma, and liquid.
The gas is the freest and most spaced particle with no fixed volume and shape. On the other hand, the particles of a liquid are a little closer than the gas but do have an indefinite shape.
The solid has particles closely packed with no space, which makes them have a definite shape and volume. When a container filled with particles is shaken, there is no movement as they are very closely packed, like solid.
Therefore, the container represents solid matter.
