Question

A tin can collapse when air is removed from it. Give reason.

Answer 1

The air inside a tin can exerts pressure against the interior surface that pushes the walls of the can outward and the air outside of the can exerts pressure that pushes the sides inward. Evacuating most of the air from inside a tin can removes the outward-pushing pressure, which leaves only the crushing force of the air outside to act on the tin can(The high pressure outside exerts more pressure than the low pressure inside). Since the greater force exerts greater pressure on the walls from outside, the tin can collapses its walls. The result is that the tin can collapses when the air inside is removed.

Answer 2

If all air of tin is taken out a vaccum is created inside the tin and the atmospheric pressure become greater due to which the tin collapses
