well nobody can answer
A question that science would not be able to answer regarding a study of glass bottles and aluminum cans might be: "Which packaging option is more aesthetically pleasing to consumers?" While science can measure preferences through surveys and analyze data, it cannot definitively determine subjective opinions or individual tastes, as these can vary widely from person to person.
glass, aluminum for bottles be more specific
Recycling
The hypothesis for this question could be: Drinks stay colder longer in cans than in bottles due to the insulating properties of the aluminum material in cans compared to glass or plastic bottles.
If a question is an ethical one about which decision is right or wrong, or what a person should do, scientists can contribute to the discussion, but it is not ultimately a scientific question. So a question about the study that a scientist would not be able to answer is, "Which one should be used more often" or something like that. -Apex
aluminum can: mineraux/ metaux glass bottle: sand=glass so sand and metal cap
radiation
Cans cool faster than glass bottles because aluminum is a better conductor of heat than glass. This allows the contents of a can to come into contact with cooler temperatures more quickly, speeding up the cooling process. Glass bottles, on the other hand, insulate the contents more effectively, slowing down the cooling process.
Most recycle centers just take plastic bottles, aluminum cans and glass bottles. You should call ahead of time before making a trip there to be sure.
Rock salt sources: Science test
They started with glass bottles.
Bottle caps are typically made of steel or aluminum. Steel caps are commonly used for glass bottles, while aluminum caps are more common on plastic bottles. Both materials are preferred for their durability and ability to preserve the freshness of the contents.
