Question

What happens to the shape of a thin hot tin can if it is closed and cold water is poured on it?

• A. Pressure inside the can is less than that outside, so it shrinks.
• B. Pressure inside the can is more than that outside, so it shrinks.
• C. Pressure outside the can is same as that inside, so the shape remains the same.
• D. Pressure inside the can is equal to the atmospheric pressure - final shape depends on the atmospheric pressure.

Answer 1

The correct option is A

Pressure inside the can is less than that outside, so it shrinks.

On pouring cold water into the hot tin can, the air inside the can gets condensed and creates low pressure. The higher pressure from outside distorts the shape of the can and it shrinks inward.
