According to the Particulate theory of matter, everything is made up of atoms which are made up of protons, neutrons and electrons.

Depending on what state the object is in, the space in between the atoms would be different. For example, in solids, they have the least space in between them as the atoms are packed very close to one another which only allows them to vibrate on the spot. In liquids, they are close to each other but still have more space to move around than in solids. In gas, the atoms have the most space to move around and are able to move about freely because of the gap between each atom.

Diffusion would occur in liquids and gases but not solids due to the space between atoms.

This movement causes the smell or color in them to spread about in a random manner.

Absolute Zero occurs at –273 Degrees Celsius, which there is absolutely no heat and nothing can move as all particles come to a stop.
