Question

What is the condition of the gravel of sand in water?Does it sinks in or it floats on water??​

Answer 1

Answer:

This is because of the surface tension of the water. Surface tension means that the water has a tough “skin” of water molecules that allow some things to float on the surface, like leaves. After a while, the sand gets wet and the water usually moves, and the sand will sink to the bottom.

Answer 2

it will sink because it implies that the force of gravity on pulling it downwards is greater than the upthrust of water on sand pushing it upwards .
