Question

Describe the crushing tin can experiment. What do you conclude from this experiment ?

Solution

Take a tin-can having air tight cap (screw cap). Remove cap and boil somowater in it, so that steam comes out and in this way air from inside goes out. While boiling replace the cap and allow it to cool. Vapours inside condense and form water creating vacuum above them. We see the can crumbles due to air pressure from outside. This proves that air exerts pressure.

  Is there an error in this question or solution?
