A student predicts that a solution of ethanol (C2H5OH) and water will have a lower density at room temperature than that of pure water. Which tools would most help the student test this prediction? Will give

It would probably be, something that can take up moisture to test it.

Explanation:

(to see if it can evaporate)

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.
