Document Summary
11-1 liquids and gases are both examples of fluids: fluids have the ability to flow, flow because their molecules can move freely with respect to each other and are not tied to fixed positions, 2 categories b. i. b. ii. Very weak intermolecular force so nothing preventing them from expanding to fill any container b. iii. 11-2 density measures the amount of mass per unit volume: density: mass of the substance divided by the volume that it occupies, formula, doesn"t tell you how closely packed the molecules are b. i. Need to know the density of the substance and the mass per molecule: ways to describe density: c. i. Compare its density to that of another substance that serves as a standard c. ii. 1. Liquid water at 4c (p= 1000 kg/m^3) and the specific gravity of a substance is equal to its density divided by that of 4c liquid water: depends on temperature d. i. d. ii.
