When a liquid is cooled, the kinetic energy of the particles. The force of attraction between the particles, the space between the particles, and the matter changes its state to solid.

As kinetic energy is the energy obtained by the molecules of a substance due to their motion.

Hence, more is the motion between the molecules more will be kinetic energy of the substance.

So, when a liquid is cooled then, kinetic energy of its molecules decreases due to which molecules tend to come closer to each other. As a result, there occurs an increase in the force of attraction between the molecules leading to decrease in space between the molecules.

Thus, we can conclude that when a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles increases, the space between the particles decreases, and the matter changes its state to solid.

For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.

Explanation:

For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.

When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles increases, the space between the particles decreases, and the matter changes its state to solid.
