1.Pure Substance is an Homogenouswhen it comes to it's appearance and also pure Substance have one Component like Homogenous.
2.When pure substance is boiled it remains constant when water is vaporized because of its sharp Boiling point and sharp Melting Point.
3. Because of its sharp Melting Point particles within the solid structure begins to break down and the solid starts to melt completely because more heat is added.
4. Liquid is an exmple of pure substance like water, because it has only one type of molecule.
5. Solid Materials can easily melt because of its energy and heat that gains to melt it faster and quickly, like steel, butter, ice and mamy more.
6. Pure Subtance has a dixed boiling point because the physical and chemical properties are totally fixed.
