Question

The pressure of the air in the can is reduced by means of a pump. The can collapses when the
pressure of the air in the can falls to 6000 Pa.
(i) Explain why the can collapses

Answer 1

The can collapses because the pressure of the air inside the can reduces to $6000 Pa$, which is below the atmospheric pressure outside the can, having an approximate value of $101000 Pa$.

This great atmospheric pressure, makes the can to crush in making the can to collapse.
