What happens to the potential energy of the molecules in a reaction? O A. The potential energy of the products is equal to that of the reactants. B. The reactants only lose potential energy when forming products. C. The potential energy of the molecules does not change in a reaction. D. The potential energy of the molecules changes during a reaction.​

first one is the correct answer

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.
