Question

state two characteristics of matter demonstrated by:(a) Diffusion (b) Brownian motion?​

Answer 1

Answer:

The zig-zag movement of small particles suspended in a liquid or a gads is called Brownian motion. Brownian motion tells us that the particles are tiny nature and the particles of a matter are constantly moving. a) Particles of matter have spaces between them. b) Particles of matter are in continuous motion.
