Question

The change in shape of a hot tin can when poured with cold water on it is due to the

Answer 1

air pressure acting on it from outside.
when the can is poured in cold water then the air in it becomes cold and its volume get decreased.
this leads to a decrease in air pressure inside the can thus the external air pressure increases and this results in crushing of the can.

Answer 2

Answer:

Atmospheric Pressure

Explanation:

The atmospheric pressure or barometric pressure is defined as the pressure in the atmosphere.

Atmospheric pressure is lower at heights and more on the ground.

This pressure is lower in cold regions or areas surrounding it and higher in warmer places.  

A hot tin contains warm air inside it to begin with. The moment it is immersed in cold water, the same air starts getting cold and the atmospheric pressure decreases.

With the situation being reversed inside the can, the outside (surroundings) remain relatively unaffected. It has the same atmospheric pressure. This is more than that of the hot tin can.

It is this pressure that compels the tin can to crumple.
