Two tin cans - P and Q, both half-filled with water are heated on two stoves till the water inside starts boiling. They are boiled for 1 minute after which the stoves are turned off.
The mouth of can P is sealed tightly with a lid immediately and placed under running tap water. The mouth of can Q is sealed tightly after 30 minutes and then placed under running tap water.
what will we observe?
Dear Student
In case of can P when water is poured , the can is crushed almost immediately. This happens due change in pressure inside the can du conversion of vapour to water due to rapid cooling. But in case of can Q the vapours are no longer left after 30 mins so when the water is poured it just cools the inside water without crushing the can.
