Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is

Element: Simplest form of matter to have unique chemical properties. Atom: The smallest particles with unique chemical identities. Nucleus: Center of an atom (composed of protons and neutrons). Proton: Have a single positive charge (+1). Neutron: Have no charge. Electron: Tiny particles with a single negative charge and very low mass (-1)/determines chemical bonding properties of an atom. Atomic Number: Number of protons in the nucleus. Atomic Mass: Approximate number of protons and neutrons

less close thus making the ice have less density than water. If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps our body (70% water) keeps the water from overheating or freezing. Absorbency The ability to take in a material Adhesion The tendency of water to stick to other substances Buoyancy The ability of a fluid to exert an upward force on an object that is immersed

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed

Photosensitive materials (x-ray films) are used to record the invisible x-ray image. It is required to reproduce all the characteristics of the invisible image in visible form .The films ability to do so depends on its sensitometric properties. Sensitometer: Measures films sensitivity to light; shows the range of densities on an image. Sensitometry:- The scientific study of the response of photosensitive material to different levels of exposure. How is it done? Producing a sensitometric strip
