Molecular Model problem 24


Very small pollen grains are suspended in water. A bright light shines from the side. When looked at through a microscope, small specks of light are seen to be moving in a random, jerky manner.




What are the moving specks of light?


  • pollen grains being hit by other pollen grains


  • pollen grains being hit by water molecules


  • water molecules being hit by other water molecules


  • water molecules being hit by pollen grains
