NCERT Question 4 - Chapter 1 Class 9 - Matter In Our Surroundings

Arrange the following substances in increasing order of forces

of attraction between the particles— water, sugar, oxygen.

Answer

We know that, 

The amount of force of attraction in different states of matter, in increasing order is as follows 

Gas → Liquid → Solid 

Since

• Water is liquid at room temperature. 
• Sugar is solid at room temperature. 
• Oxygen is gas at room temperature. 

Hence, the amount of force of attraction in the above-mentioned things, in increasing order is as follows

Oxygen → Water → Sugar
