3. increases
4. remains the same

Q. In the experiment to demonstrate that air exerts pressure, when ice cold water is poured over a sealed tin can containing hot air, the can collapses. Pick the correct explanation for the experiment.

1. The can collapses because the pressure inside the can falls below the pressure outside the can
2. The can collapses because the pressure outside the can falls below the pressure inside the can
3. The air pressure inside the can is same as the pressure outside the can
