Brownian motion
Physics · Secondary 4 · Medium · Brownian motion
Two sets of pollen grains, one large and one small, are suspended in the same still water at room temperature. How will their Brownian motion compare?
- Smaller grains show faster, more noticeable random motion.
- Larger grains show faster, more noticeable random motion.
- Both sets of grains stay almost completely at rest.
- Both sets of grains move only upwards in straight lines.
