because it may have an adverse reation to the metal, for example and acid would react with the metal and disolve it!
a perfectly claen container
A metal container will work, a chimnea would work perfectly
it would melt faster in a glass container faster.
The fact that a metal (mercury) is a liquid at room temperature is a characteristic property of the metal, mercury. The temperature at which a metal melts to become liquid would be a chemical property of the metal.
In a chemical plant it would be a blend tank or reactor. In a laboratory it would be a reaction flask or beaker
would test a chemical pproperty of a metal object
Rust its self is a chemical change, but a chemical property for a car would be that it gets rusty over time.
Chemical Yes. The metal is being converted to an oxide of that metal. Most would (correctly) describe this as a chemical change, but physics has a lot to do with how that happens.
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
No, a metal bar glowing red hot in a fire would be an example of a physical change, not a chemical change.
Metal or Glass would best, but for long term storage it would be best to keep it in the original container it came in. The original container would be specially made for the purpose.
this chemical reaction forms a gas that may rupture the container or explode.
