Question

It is esier to walk throgh air than throgh water.why is it so?

Answer 1

because of byount force.

Answer 2

The molecules in the air are loosely packed with one another. So when you move, the loosely packed molecules give way to the tightly packed molecules (ie your body).

In the case with water, the molecules are tightly packed than the air molecules. So when you try to move in water it produces a certain resistance which has to be broke for movement.

Solid substances have very tightly packed molecules.
