Match the following vocabulary words. Match the items in the left column to the items in the right column. 1 . kinetic energy graph showing how phases are affected by changes in temperature or pressure 2 . phase equilibrium the theory that attempts to explain gas behavior at the molecular level 3 . Kinetic Molecular Theory the temperature and pressure at which all three phases exist simultaneously 4 . phase diagram a dynamic situation when the number of molecules leaving the liquid is greater than the number returning 5 . triple point an indicator of average kinetic energy 6 . temperature the state achieved when the exchange of molecules between two phases occurs at the same rate 7 . evaporation the energy of motion which is represented as K. E.=1/2 mv 2 where m = mass, and v = velocity of the particle in motion

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
