It is moisture and air that causes metal to rust, therefore if something is air tight and doesn't get much air it can't easily rust.
Because It will be in contact of oxygen
iron
It stays the same
When a piece of iron is placed in hydrochloric acid, the products are Iron (II) chloride and hydrogen gas.
Yes, but in a glass container as it can corrode metals and leak out of an Iron container
No, iron oxide weighs more than pure iron. The iron will pick up the extra mass of the oxygen molecules that bond with it.
When molten or gaseous, yes.
Iron conducts heat better than other metals so it heats up the potato faster.
iron travels faster
iron
It stays the same
iron rusts faster in presence of moisture and air.

iron
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Sound travels faster in iron. Usually sound travels faster in media with higher density. Also presence of lattice makes difference too.
