5. The accepted values for density are: aluminum= 2.7gom: PB = 3000039 and iron = 7.87 g/cm". Compare your values from Question 4 with the how do they compare? Why are they different? Note: the density of different kinds of PEG PVC because of the difference in the arrangements of their molecules.​

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.

it is the most commonly accepted one
