Question

3. How will you show that soil contains air?​

Answer 1

Answer:

Take soil and pour water over it and within few seconds you will see few bubbles. These bubbles came due to the air spaces in the soil particles. The water filled up the spaces which were earlier filled with air. Now these air particles rise up as bubbles as air is lighter than water.
