Question

Which of the following activities proves that particles of particles of matter have space between them?
(A) dissolution of sugar into water
(B) dilution of potassium permanganate solution
(C) breaking the stream of water
(D) none of the above

Answer 1

Hint: All matter is made up of particles that are incredibly small - much too small to see with the naked eye. The particles can be atoms or combinations of atoms that are bonded. There are forces between the particles. The particles in matter are always moving:

Complete step by step solution:
We have been provided particles of matter:
We need to name the activity that proves that the particles of matter have space between them,
It is true to say that particles of matter have space between them. As physical properties of matter states that matter possesses space between its constituent particles. So, it goes into the small spaces present in between water molecules.
Following activity can illustrate the above phenomenon,
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. When one of these solid dissolves in water, the ions that form the solid are released into solution, where they become associated with the polar solvent molecules.
Dissolving sugar in water is an example of a physical change. A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. If you evaporate the water from a sugar-water solution, we would be left with sugar.
So, from this we can say that the dissolution of sugar into water proves that particles of matter have space between them as the sugar particles get trapped in the molecules of water.

Therefore, option (A) is correct.

Note: Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
