what do metals contain and how do they move around?
some electrons which move freely around metal atoms and they can carry electric current and take it to one end to another
what are metals and what is the meaning of it?
thermal conductors and it means that they let heat energy pass trough
what will happen when you heat a piece of metal?
particles vibrate strongly
what is one of the reason why the particles vibrate when a piece of metal is burnt?
close together
what do free electrons do?
help to transfer energy from the hot side to the cooler side of the metal
