Robert Boyle did not believe that water was one of the basic elements that all substance was made of. To test this, he conducted an experiment where he ran an electric current through water. He placed two test tubes above each of the terminals of the electricity source and collected the gas that came out. He repeated the
experiment a total of three times, each time using the same amount of water and the same level of electric
current. These are his experimental results: what is the dependent variable in this experiment

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 .
