Some Physical Properties
Conductors are objects that let heat through. Some conductors are steel, brass, bronze, dirty water, and mercury. There are more things but that is just some. Insulators are objects that stop heat from going through. Some of them are oil, fiberglass, (dry) cotton, (dry) paper, and diamond, and many more. Mass is the amount of matter in a object. Heat is a fundamental thermodynamic process in which an amount of energy flows spontaneously from hotter temperature to colder objects. Density is the degree of compactness of a substance.
