Answer 2

Answer:

A rubber pressed on a flat surface sticks to the surface because air pressure inside it is less than the air pressure outside.

→ A rubber pressed on a smooth surface gets stuck to the surface because of air pressure.

→ When pressed against a flat smooth surface like a wall, air is forced out between the surface and the wall.

→ This reduces the air pressure in the space between the surface and the wall in comparison to the air pressure outside.
