Think of the air around us as a huge ocean of air that sits ontop of the land. Air has weight...incredible weight. If you take the air out of something, the there is a vacuum inside it and nothing to support it and the air pressure crushes it
Steel cans can be removed from rubbish using magnets because steel is a ferrous metal that is magnetic, while aluminum is not magnetic. The magnets attract the steel cans, allowing them to be separated from other materials in the rubbish.
Yes
idkk... -_-
Compressed air cans freeze when in use because the rapid release of compressed air causes a drop in temperature, leading to the formation of ice on the canister.
It means that the air pressure that sealed the can - can not be removed

1. Steel cans arrive at a recycling center. 2. The cans are removed from the conveyor belt with an electromagnet. 3. The cans are smashed and baled. 4. The steel cans are delivered to a facility where they are melted and cast into ingots. 5. The steel ingots are rolled out into sheets. 6. These sheets are delivered to manufacturers that turn them into new cans.

If both bags are the same size, there would be more cans in the crushed can bag and it would weigh 3 or 4 times more than the bag without any crushed cans. If there are the same number of cans in each bag, as long as the cans were not closed, they would weight the same. If the cans were sealed, the air inside would add to the weight of the bag. as the uncrushed cans would leave a lot of air in the bag that would be lighter so a bag of crushed would weigh more as there would be more cans in there
