 a. decreases the gas pressure by slowing the gas particles.
  b. does not affect the gas pressure.

Question 2

This figure depicts pollen grains suspended in a liquid exhibiting a continual, erratic motion known as Brownian motion. Albert Einstein inferred that atoms exist based on his calculations that described this type of motion. What was the basis for his conclusion?
 a. The erratic motions of the pollen grains were explained by Einstein to result from random collisions with water molecules.
  b. The tiny grains could be shown to be atoms.
  c. The existence of atoms was an inescapable conclusion of his theory of relativity.
  d. The existence of atoms was an inescapable conclusion of his theory of the photoelectric effect.
  e. The existence of atoms was an inescapable conclusion of his theory of heat capacities of solids.
