Question

5. When sugar is dissolved in water, the volume of water remains the same. Why?

Answer 1

Explanation:

When sugar is dissolved in water, the volume does not remain the same. As a soluble material is added to a solvent, it's molecules become surrounded by the solvent molecules and the volume increases slightly.

Answer 2

⏹ The above statement proves a very important properties of matter, that is the particles of matter have spaces in between them. For understanding the above statement, we need to know that:

• Matter is particulate in nature.
• Particles of matter have spaces in between them.

The matter is made up of extremely small particles known as atoms. The atoms are very small beyond our imagination. They have spaces in between them which is known as Interparticular spaces or voids.

✏ The extremely small particles of sugar positioned themselves in the small spaces between the particles of water. This also accounts to the fact that the level of water doesn't rise and there is no change in volume. This is because the particles do not displace it but occupy the small spaces between the particles of water.

✳ Other properties of matter are:

• Particles of matter are continuously moving.
• Particles of matter attract each other.

The above properties along with the 2 other properties mentioned in the question can be proved by $\large{\rm{experimentation}}$. Like for proving matter is particulate in nature and have space in between them, we use the sugar and water experiment. It is tough to break iron, because the particles are strongly binded by interparticular attraction force. Diffusion of anything proves that particles are continuously moving.
