Diffusion<span> is the spread of particles through random motion from regions of high concentration to regions of lower concentration. Because </span>diffusion<span> works without barriers, when </span>smoke<span> is emitted into the air, it can easily travel to surrounding areas. hope this can help you ^_^ </span>
Conductors (something that allows electricity to flow easily) allow for electricity to flow easily. This would be the wires. If you don't have conductors, then you cannot have electricity flow.
Insulators (something that doesn't allow electricity to flow through it) is important because it allows us to be able to touch the cables or place them next to one another and not shock ourselves
Hope this helps
