- 4. WHAT IS PHYSICAL PROPERTIES? A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its transformations or evolutions between its momentary states. Physical properties are often referred to as observables. They are not modal properties. 7/18/2016 12:29 PM 4
- 5. VOLUME Volume is the quantity of three-dimentional space enclosed by a close surface, for example the space that is a substance or shape that occupies or contains. 7/18/2016 12:29 PM 5
- 7. DENSITY The Density is a substance is it’s mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume. At the image the ρ is the density, m is the mass, and V is the volume. 7/18/2016 12:29 PM 7

- 9. BOILING POINT The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For a given pressure, different liquids boil at different temperatures. 7/18/2016 12:29 PM 9
- 11. MELTING POINT The melting point (or, rarely, liquefaction point) of a solid is the temperature at which it changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure. 7/18/2016 12:29 PM 11

- 13. METALLIC PROPERTIES Metallic Properties are malleability and ductility. Malleability is the capability of a material to be hammered into thin sheets. Ductility is the ability of a material to be drawn into wires. 7/18/2016 12:29 PM 13

- 16. HARDNESS Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied. Some materials, such as metal, are harder than others. Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behaviour of solid materials under force is complex; therefore, there are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. 7/18/2016 12:29 PM 16

- 18. WHAT IS CHEMICAL PROPERTIES? A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected greatly for its chemical properties to be investigated. When a substance goes under a chemical reaction, the properties will change drastically, resulting in chemical change. 7/18/2016 12:29 PM 18
