Answer 2

When a test-tube full of water is-

(a) Poured on the cemented floor

• The water will stay on the surface and will not be absorbed into the floor.
• This is because the cemented floor is non-porous.
• It does not allow any liquid to penetrate the surface.

(b) Poured on soil in a flowerpot

• The water will go down the surface and will be absorbed easily.
• This is because the soil is porous.
• It allows liquids to penetrate its surface.
