The heat changes it. If it was in a tube on the stove it would change into a liquid and once it is on there for a while it changes into a solid. Because you can smell iron that is proof that it can be a gas. And because you know there are things made out of iron you know they can be melted!!
Examples of matter: water, air, iron. Non-examples of matter: light, sound, thoughts.
There are 3 basic states of matter Solid Liquid Gas
There are 4 states of matter not 3. These are: solids, liquids, gases and plasma.
The three states of matter are solid, liquid and gas
they require a substance to use to make the 3 states of matter with.
Matter
the change of matter are the physical and chemical change physical change is a substance that do not change. chemicalchange is a substance that change. examples of physical: crumpling of paper evaporation of liquid examples of chemical: digestion of food burning of wood
iron exhibits two oxidation states. one is Fe(II) and other Fe (III)
the 3 states of matter are solid, liquid and gas.
Solid, Liquid, Gas
The element with oxidation states of +2 and +3 only is chromium (Cr).
"Type" is ambiguous in this context. Do you mean isotopes? Or do you mean states of matter? (Helium has some exotic states of matter.)Wikipedia states that there are 8 helium isotopes, to of them (3-He and 4-He) stable."Type" is ambiguous in this context. Do you mean isotopes?
