Is it a gold ring? A friend shows you a gift she has received and says it is a gold ring! In the laboratory, you find its mass to be 70.25 g and its volume to be 3.64 cm^3. Is her new ring pure gold? Why or why not? The density of pure gold is 19.3 g/cm^3. d=m/v

it's filtration, but this is an assumption so my apologies if i got this

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
