Surface tension describes 1. the forces of attraction between surface molecules of a solvent and the solute molecules. 2. the forces of attraction between the surface of a liquid and the air above it. 3. the resistance to flow of a liquid. 4. the inward forces that must be overcome in order to expand the surface area of a liquid. 5. capillary action. 6. adhesive forces between molecules.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
