Explain how you know that heating the iron and sulfur together in the test tube results in a new compound composed of chemically combined iron and sulfur.

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.

so what is the problem with your lab report and whats the subject of the lab report? i will you
