Because rhubarb is slightly acidic so it reacts with the steel creating a gas
When rhubarb reacts with steel cans, the gas formed is hydrogen gas. This reaction occurs due to the acidic nature of rhubarb, which can corrode the steel cans and release hydrogen gas as a byproduct.
The acids in the fruit would react with the steel, creating hard swells or leakers. Cans now are lined with coatings that delay such reactions.
The gas in steel cans of rhubarb is a by-product of a natural process wherein methane forms in the colon and is secreted through the rectum and anus. If properly captured, this gas can be stored indefinitely in the steel can for later use.
Cans which are made from steel, are electroplated with tin. (This is safe for storing food)
Not if it's in cans.

Carbon dioxide gas is formed in steel cans when storing fruit. This occurs due to the respiration process of the fruit, where oxygen is consumed and carbon dioxide is produced in the sealed environment of the can.
The steel cans will be attracted.
Aluminium and steel cans can be separated using a magnet, as steel is magnetic while aluminium is not. By running a magnet over a pile of cans, the steel cans will be attracted to the magnet while the aluminium cans will not, allowing for easy separation.
It depends on the can. Soup cans might contain steel. Soda cans are made of aluminum.
