2 a metal is ductile

3 a metal is opaque

4 a metal is brittle​

4. A metal is brittle

Explanation:

As they are heated, metals generally become less brittle, allowing for plastic deformation. In other words, most metals become more ductile when they're heated and can be more easily drawn into wires without breaking.

Explanation:

The term 'brittle' means “hard but liable to break easily”. If a material is brittle, it means that when it is subjected to stress, it breaks with little elastic deformation and without significant plastic deformation. ... Metals are not generally brittle. Rather, they are malleable and ductile.

ahhh yay, i need it lol hope i get it : )

we could tell by the rotten smell, that something putrid was in our trash can.
