Because steel will react with the food and could oxidize (Rust), which could penetrate the can and allow in bacteria to contaminate the food.Actually most modern "tin" cans contain no tin, the steel is coated with a protective layer of plastic instead.
Tin and enamels (lacquers) are used to coat cans. See Related Links.
Tin cans are not made entirely of tin, and the name "tin can" would be more accurate if it were "tinned can". The can is actually made of steel, plated on the outside with tin. The steel gives the can strength, and the tin plating helps to protect the steel from rusting. As your question indicates, there are situations in which the tin is not entirely successful in preventing rust. Aluminum cans are more naturally resistant to corrosion, and are also more easily made, because aluminum is more easily formed into a can than steel is.
Depends on the metal used but it can be coated with tin, paint or paper.
Tin is an element, but you have to be careful because many people use the term loosely. They sometimes mean simply 'metal' and sometimes iron coated with tin to prevent rusting, and by extension, iron coated with anything else.
steel cans are coated in tin so whatever is in the tin does not react with the metal
They are made from steel with a thin coating of tin to prevent corrosion.
Sheet aluminium, or tin coated rolled steel.
The can is made of steel, thinly coated with tin or another non corrosive metal. If the can gets scratched, then the steel can start to rust.
No, they are usually made of aluminum, frequently from recycled aluminium. They can also be made of tin-coated steel.
Nope - they're made from steel, coated in tin.

They're not - or not any more. When it was done (a century ago) it was to prevent the steel of the cans from rusting.
A tin-plate is defined to be a thin sheet of iron or a steel alloy that is coated with tin. This helps prevent the steel from rusting. They are most commonly used to make cans and pots.
because the steel itself will react with the food and the rust can get in the food so tin is used because it doesn't react with liquids so it wont rust.

Steel cans are coated with tin (a less reactive metal) to prevent a chemical reaction so nothing will happen to a dented steel can if there are baked beans which are acidic in it.
