Answer:
Conductor
Step-by-step explanation:
All substances on Earth are made up of matter which can be in the form of a solid, liquid or gas. Matter is also classified based on properties into Metals or Non-metals. These two groups, depending on their ability to transfer heat and temperature are classified into either CONDUCTORS or INSULATORS.
A conductor is an object that can conduct heat and electricity. They are usually solids that can endure heat i.e have high melting and boiling points. They transfer heat easily between surfaces. Example of a conductor are iron. Insulators, on the other hand, are poor conductors of heat and electricity. Hence, cannot transfer heat. Example is plastic.
