You are about ready to start an experiment in which you must use a sharp razor blade to cut a flower stem in half. what are two safety rules you must follow in this investigation?

astronomers such as edwin hubble.

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 .

it means there are 3 atoms of oxygen
