Question

Sand settles down in the water. (True or False)

• A. True
• B. False

Answer 1

The correct option is A True

Sedimentation:

• The process of settling down of heavier insoluble particles at the bottom of a liquid is called sedimentation.
• The heavier insoluble particles that settle down at the bottom of the liquid are called sediments.
• Sand is heavier than water, i.e. its density is more than that of water.
• When we mix sand and water, no reaction takes place.
• The sand simply settles down at the bottom of the water container.
• This is because sand is heavier than water and hence cannot float in water and this process is known as sedimentation.

Therefore, the statement sand settles down in the water is true.
