Why do tin cans get crushed if cooled after heated and closing is mouth?
Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.
If a tin is filled with hot water and sealed then covered with cold water What causes the tin to become dented?
The outside air pressure dents the tin. The water or air inside a sealed metal container will contract when cooled from the outside (by conduction through the can). When it was sealed, the pressure on the inside was the same as on the outside. But the contraction reduces the pressure on the inside, causing the external air pressure to squeeze the can, and possibly cave it in. This is widely demonstrated in another experiment using dry ice. A sealed gasoline can of about a gallon (4 liters) is placed on a dry-ice bed and cooled until the outside air pressure crushes the can.
Where is the fulcrum on a diagram of a screwdiver opening a paint can?
Very close to the tip of the screwdriver. The lip of the tin that the screwdriver presses down against is the fulcrum. The load is the tin lid, under the lip of which the tip of the screwdriver sits.
How did tin get its name?
From the Anglo-Saxon word tin. Tin's atomic symbol comes from the Latin word for tin, stannum
Are tin whistles made with tin?
Well tin whistle today are now made with nickel,brass,silver,or wood. It's not made with tin. The tin whistle is named so because before it was made with tin-plated steel.
Why would a lid of a tin be pushed of because of gas molecules?
A lid of a tin can be pushed off due to gas molecules because of the buildup of pressure inside the container. When the contents of the tin are heated or if a chemical reaction occurs, gas molecules are produced, increasing the number of gas particles. As these gas molecules collide with the lid, they exert pressure on it; if this pressure exceeds the adhesive forces holding the lid in place, the lid will be pushed off. This phenomenon is commonly observed in sealed containers when the contents undergo changes that generate gas.
How is a tin can made?
A tin can is typically made from a thin sheet of steel or aluminum that is cut into a flat piece. The flat piece is shaped into a cylinder and welded or soldered along the seam. A top and bottom lid are then added and sealed to create a sealed container.

The tin lid in your family is your kid :)

What happens when tin oxide decomposes into two products when heated?
When tin oxide (SnO) decomposes upon heating, it forms tin metal (Sn) and oxygen gas (O2) as the products. The reaction can be represented as: 2SnO -> 2Sn + O2.
Why is it easy to open the lid of a paint tin with a screwdriver?
Opening the lid of a paint tin with a screwdriver is easy because the lid is typically designed to fit snugly, creating a seal that can be broken with leverage. The flat edge of the screwdriver can be inserted into the small gap between the lid and the tin, allowing you to pry it open. This method effectively uses the screwdriver as a lever, amplifying the force applied and making it easier to overcome the seal. Additionally, the materials of the tin and lid are often designed for easy access, facilitating quick opening.
Why did the fish tin lid?
Because the Ice-Cream had no bones. HaHaHaHa...
Why does the mass of tin increase when tin is heated in air?
When tin is heated in air, it can react with oxygen to form tin dioxide (SnO2). This compound has a higher mass than the original tin due to the addition of oxygen atoms from the air. As a result, the overall mass of tin increases when it undergoes this chemical reaction with oxygen in the air.
What is coffee-can lid?
A coffee can lid is just that, a lid that cap a tin of coffee grounds or beans. In older cans and more high quality grades of coffee, the can and lid are made entirely of metal. Modern convenience and mass production usually sees coffee can lids now made of plastic, much like a peanut tin lid, complete with a peel-back metal seal.
How many moles of tin metal will be produced when 0.74 moles of tin IV oxide is heated?
The formula for tin (IV) oxide is SnO2. This formula shows that each formula unit contains exactly one tin atom. Therefore, if 0.74 mole of tin (IV) oxide is heated sufficiently to cause complete disproportionation of the compound to its constituent elements, 0.74 moles of tin metal will be produced.
When was coffee first sold in sealed tin cans in US?
1879
Do anchovies in a unopened tin spoil?
No it won't because it is vacuum sealed
