Hot waters in the cans has their molecules expanded because of the heat. To make the cans contract, it must be fully sealed after the heating. When the cans is suddenly cooled down, the waters molecules contracts swiftly thus leaving an empty space inside the can. This lower the pressure inside the can, lower than the atmospheric pressure. Than the atmospheric pressure just simply acts upon the can and crushed the can to death. Hahaha...
But if you leave the can to cooled down normally, there is no significant contraction because the can has some times to regulate the pressure by making a small leak on the seal, depends on what type of seal used.

∙ 13y agoWhen a can with boiling hot water is placed in cold water it crushes, as the vapors of boiling hot water in the can condenses & create vacuum in the can, so the air from outside forces the can walls to fill the vacuum. That air force crushes the can.

∙ 12y agoIf you boil water in a pop can, the air is replaced by steam. If you put the can, inverted, into ice water the steam condenses. Steam occupies approximately 700 times as much volume as water. That decrease in volume creates a vacuum within the can. Water from the bowl of ice water cannot enter the can fast enough to equalize the pressure because the opening is too small to allow efficient flow so, the atmospheric pressure crushes the can.
The same thing happens, occasionally, when tank trucks are steam cleaned and the man holes are closed before the steam cools. As you might imagine, that is much more spectacular.

∙ 12y agoThe hot air contracts when placed in the cold water as the water is blocking the air from going in, the decreased air pressure sucks in the soft aluminum sides and collapses the can.

What replaces heated air at the equator?
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Why does ink dissolve into cold water?
Because the particles in the ink when heated can move around and are more active when the water is hot.
Water vapor and air inside an aluminum container are heated to a high temperature The container is then submerged in ice cold water Why does the aluminum container collapse?
When water is heated, water vapor forces the air out. When submerged in cold water, the water vapor condenses instantly, leaving a partial vacuum in the can, Atmospheric pressure (14.7 psi) acting on the outside of the can crushes the can before air can rush through the opening in the can to balance the pressure. Fun science experiment, just be careful not to get burned.
Is yellow when heated and white when cold?
Zinc oxide
What is the term a hydrate with the water heated off?
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
Why does a can with boiling water in it implode when put into a bucket with cold water in it?
because the hot water in the can mix causing steam filling the can with gas. that puts too much pressure on the can and it implodes to get rid of the gas inside
Does water flow from hot to cold?
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
What happens to a can when heated and transferred to cold water?
The can collapses and closes in on itself.
Is hot water denser than cold water?
NO, it is the opposite. remember molecules expand when heated
What metal does not react with cold water but reacts with steam when heated?
Iron and Zinc
What happens when you repeatedly heat up granite and then plunged into cold water?
the granite will get hot from being heated repeatedly and you will get cold from plunging into cold water. not sure why you you want to do either.
How is matter heated by conduction?
it is heated when cold air meets and cools down hot air and freezes water so it turns to ice
How are currents that form in heated air similar to currents that form in heated water?
Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
Can i add warm water to my beta fish's tank?
no WARM WATER IS NOT AS PURE as cold water as it goes through difeernt pipes to get heated.
Why water is generally heated from the bottom?
Warm anything, air or water will rise. Cold water is put at the bottom of the tank through a tube inside the tank. The water is heated and rises and is taken out of the top. The inside of the heater is open, it is just a hollow tube. That is why the hot water gets slowly colder, more cold water is being mixed with the hot in the tank.
When an electric kettle is switched on it will take a few minutes to heat the water how does the element at the bottom of the kettle heat all of the water?
As water at the bottom is heated, it rises and cold water replaces it. That's heated and the cycle continues until all the water is at the same temperature.
Why is it that when you put the left in cold water and the right hand in hot water and take both out and put them normal water why does the left hand feel hot and the right feel cold?
If you have a heated item and put it in a normal temperature water, it feels cold because the hot water may feel so hot that it is cold. It's the opposite for the cold item.
