question 53

Multiple Choice

A physics student looks into a microscope and observes that small particles suspended in water are moving about in an irregular motion.Which of the following statements is the best explanation for this observation?

• A)Water molecules strike the particles giving them the same average kinetic energy as the water.
• B)The particles are carried by convection currents in the water.
• C)The small particles may be considered a fluid;and thus,move about randomly.
• D)The actual motion is regular,but the speeds of particles are too large to observe the regular motion.
• E)The particles are moving to be uniformly distributed throughout the volume of the water.
