Question

Give reasons for the following:-(a). We can walk through air.

Answer 1

Answer:

Solid substances have very tightly packed molecules. And you already know that you cannot walk through a wall. 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.
