Question

How does the particle theory help to explain the difference between a drop of cold water and a drop of hot water?

When a substance is cooled, what happens to its particles?

Answer 1

Answer:

According to the particle theory of matter, the molecules in the hot water must be moving faster than molecules in a drop of cold water.

When a substance is cooled, its internal energy decreases: the movement of its particles decreases. bonds between particles form when a substance condenses or freezes, or sublimes to form a solid from a gas.

Answer 2

the difference between a drop of cold water and hot water can be explained by the kinetic theory of matter.

Explanation:

• When water is heated then energy transmitted to the molecules is present in water filter as a result of this the kinetic energy of the molecules increases.

• As a result of this they start moving rapidly and there is increase in the size between the molecules.

• However when the water is cooled is loses a significant part of energy and as a result of this ,the movement of the molecules also decreases.
