(a)
Interpretation- To explain the inward collapsing of the can on kinetic theory.
Introduction-
Kinetic theory: It explains the motion and interaction of atoms and molecules of gases.
The assumptions of the kinetic theory are:
- Gases contain a large number of particles (atoms and molecules) that are hard, spherical, and constantly in motion.
- Particles of gases are point masses; hence, they have negligible volume as compared to the volume of the container.
- The force of attraction is none between particles as well as between particles and the wall of the container.
- The collision present between particles and between particles and the wall is elastic, which means no energy is lost.
- The average kinetic energy depends on the temperature of the gas.
(a)
Explanation of Solution
When the can is heated, water converts to the gaseous state, steam. The steam covers the space creating pressure inside the can
When the sealed can is dunked in water, the temperature of the can and the particles inside it decreases. The steam condenses back into the water. This decreases the collision and pressure inside the can. The pressure inside the can decreases more than outside. Therefore, they can be collapsed due to more outer pressure than inside the can.

(b)
Explanation of Solution
Since the can is dry now, the result would be not the same as a can filled with water. There is not much change in the volume of air converting from hot to cold. Hence, the pressure does not change much. There will be a slight change in the inside and outside pressure difference. Therefore, the result will not be the same as that of a can filled with water. Either the can collapses is less dramatic or it may not collapse.
