Frage 3
Frage
Brownian motion is the [blank_start]random[blank_end] and erratic motion of molecules in the air. It provides the evidence for the presence of [blank_start]gases[blank_end] in the air which are too [blank_start]small[blank_end] to see. Experiments using smoke grains allows us to deduce that gases in the air must be moving much [blank_start]faster[blank_end] than the smoke grains.
