When discussing class data, Jack notices a trend: The difference between the experimental value for the specific heat and the accepted value for the 100% propylene glycol solution (pure propylene glycol) is higher than the others . Provide an explanation for why this might be true. Hint: What other values increase as the concentration of propylene glycol increase

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
