Brownian motion may be shown by shining light on smoke particles in a sealed, transparent container. When the particles are examined with a microscope, bright points of light are seen to move in a continuous random manner. Which conclusion cannot be drawn from this observation?
- AAir molecules are in constant motion.
- BAir molecules are in random motion.
- CAir pressure is due to air molecules colliding with the container.
- DThe mass of an air molecule is much less than the mass of a smoke particle.
