Question

properties of water
which of the following property of water explains why a wet glass slide sticks to laboratory counter?
multiple choice
water is adhesive.
water can alternate between solid, liquid, and gaseous states.
water has a high heat capacity.
water is a good solvent.
water is cohesive.

Explanation:

Adhesion is the attraction between water molecules and other substances. A wet glass slide sticks to the counter because water molecules (on the slide) are attracted to the counter's surface, showing water's adhesive property. The other options: water's state change (B) relates to temperature, high heat capacity (C) to heat absorption, being a good solvent (D) to dissolving, and cohesion (E) is attraction between water molecules (not between water and another substance), so they don't explain the sticking.

Answer:

A. Water is adhesive.
