Lisa has a glass that has a mass of exactly 100 grams. She puts exactly 45 grams of acid in the glass, and then she adds 15 grams of crushed limestone. When the limestone touches the acid, it makes bubbles. Lisa waits until the reaction stops, and then she weighs the glass and its contents. What should Lisa expect to find about the mass of the glass and its contents when she puts it on a scale?

explanation:

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.
