How do we know atoms and molecules are in motion?

One of the big problems in chemistry is our dependence upon our five senses (macroscopic observations) to infer what occurs on the atomic and molecular level (microscopic behavior of matter). Give two examples of observations we can make on the macroscopic level that prove to us that atoms and molecules are in motion.

12. For each of the four problems below, consider the two pairs of atoms/ions/molecules. Which pair (i or ii) would be attracted to one another by the strongest intermolecular interaction? Justify your answer, making sure to name the type(s) of intermolecular interaction(s) that are involved in each case. You will receive no credit without a proper justification. a. (5 points) i) Two argon atoms OR ii) two xenon atoms? b. (5 points) i) Two NH3 molecules OR ii) two PH3...

To derive the ideal-gas equation, we assume that the volume of the gas atoms/molecules can be neglected. Given the atomic radius of krypton, 1.1 Å, and knowing that a sphere has a volume of 4πr3/3, calculate the fraction of space that Kr atoms occupy in a sample of krypton at STP. Express your answer using two significant figures.

a) Langevin theory of paramagnetism assumes that atoms or molecules with magnetic moment do not interact with each other and are only affected by the applied field and thermal provocations. That would cause Curie's law. In 1907, Pierre Weiss explained that each magnetic moment interacts with each other. He suggested that this interaction could be explained by an imaginary molecular field (Hm = ?M). By using molecular field expression derive ?= C/T-θ for magnetic susceptibility. b) Plot the temperature-dependent curves...
