PHYSICAL those PROPERTY properties Extensive can be that are not Properties are measured dependent on those that and observed the amount of depend on without matter rather amount or changing the they depend quantity of composition on the kind or matter. or identity of quality of Examples: the matter Volume, Mass, substance. Length Examples: Texture, Color, Hardness, etc.  THE PHYSICAL PROPERTIES OF MATTER 1. COLOR describes the physical appearance of the substance like a red apple. 2. TEXTURE describes how it feels like smooth, hard, and rough. 3. MASS refers to the total quantity of matter present in an object like 100g of meat. 4. VOLUME is the measure of the amount od space occupied by an object. It is a three-dimensional and it involves units that have been cubed such as ft3, cm3, in3, etc. 5. ELECTRICAL CONDUCTIVITY is a measure of how well electric currents move through a distance. 6. THERMAL CONDUCTIVITY is the rate at which a substance transfers heat. 7. DENSITY is the measure of the amount of mass in a given amount of volume. THE PHYSICAL PROPERTIES OF MATTER 8. SOLUBILITY is the ability of a substance to dissolve in another substance. 9. MALLEABILITY is the ability of a substance to be rolled or pounded into various shapes like aluminum, gold, and iron. 10. MAGNETIC ATTRACTION can be observed when a metal attracts another metals. 11. HEATING PROPERTIES like melting point and boiling point  LESSON 1: PROPERTIES OF MATTER B. CHEMICAL PROPERTIES are those that result in the change Examples: in Flammabili composition ty, resulting to the Reactivity formation of new substance. Changes Matter Undergoes Chemical Change is a change in the chemical composition of a compound thereby creating a new substance. Examples: Burning of wood, digestion, sulfur burns in air Physical Change is a change in form, size or shape without changing the chemical composition. Examples: cutting of wood, folding a paper, boiling of water, etc. Exercises: Identify the following as Physical or Chemical Change 3. Toasted 1. Cremation 2. Fusion of ice marshmallow at the campfire 4. An apple cut 5. in half Condensation Identify at least 5 substances in your house particularly in the kitchen (condiments), give their chemical name, chemical formula, and  Substances Chemical name Chemical formula Use/s 1. 2. 3. 4. 5. THINK !: How Important is Chemistry to life? Lesson 1.1 Formula of Common Substances  Some Common Substances at Home and their Corresponding Common Names Formula Chemical Name Chemical Formula Baking soda Sodium Hydrogen Carbonate NaHCO3 Baking powder Or Sodium bicarbonate Table Sugar Sucrose C12H22O11 Table salt Sodium Chloride NaCl Lime Calcium Oxide Cao  Some Common Substances at Home and their Corresponding Formula Common Names Chemical Name Chemical Formula Vetsin Monosodium C5H8NO4Na glutamate Vinegar Acetic Acid/ Ethanoic CH3COOH Acid Muriatic Acid Hydrochloric Acid HCl Bleaching Agent Sodium Na2H3CO6 percarbonate  Categories of Consumer Products 1. Food and Nutrition. The food that Lesson 1.2 we eat is a mixture of various chemicals 2. Detergents and Soap. We use Consumer detergents and soaps for cleaning, bathing and washing. These detergents Products: and soaps contain chemicals with cleaning properties. Components, 3. Medicine and Drugs. These are made up of chemicals that are produced Use, Safety, in pharmaceutical industries. 4. Raw materials. These are the Quality and materials used in primary production or manufacturing of goods such as wool, Cost silk, glass, fiber, nylon, etc. Lesson 1.2 Consumer Products: Components, Use, Safety, Quality and Cost 5. Building Materials. Chemistry governs the performance of buildings. Coating materials like acrylics, silicones which decreases heat transfer. Insulators, Vinyl tiles, Polymers, etc. are important building materials in Chemistry. 6. Paper and Pulp Industry. Responsible in the production of paper. But it should address environmental challenges. 7. Fuel Industry. Petrol, diesel, LPG, kerosene, oils, are fuels produced from complex refining process which make transportation and cooking easier.  8. Batteries. Are used in cars, cell phones, laptops, watches, etc. the energy stored inside a battery is stored Lesson 1.2 in the form of chemical energy. Consumer 9. Environmental Chemistry. The Products: central subject in the study of environmental conservation Components, Use, Safety, 10. Forensic Chemistry. It helps to Quality and identify criminals by detecting chemical evidences left behind the Cost criminal scenes.  Therefore:  Chemistry plays an essential role in the products and technologies we use every day, from vital ingredients in consumer products to raw materials in manufacturing processes.  These chemicals must be produced and used in ways that protect human health and the environment.  Lesson 1.3: Separation Techniques Magnetic Distillation Centrifugation Separation Evaporation Winnowin Decantation Threshing Handpicking g Filtering Sieving Chromatography  What is Distillation? What are the Types of Distillation?  Simple Distillation  Simple Distillation is used to separate a solvent from a solution. It is useful for producing water from salt solution.  Itis used in oil refineries to separate the complex mixtures into fractions that contain similar boiling points, molecular weights and properties  Centrifugation What is centrifugation ? IS A METHOD OF CENTRIFUGATION SEPARATING IS USED TO MOLECULES HAVING DIFFERENT COLLECT CELLS DENSITIES BY TO PRECIPITATE SPINNING THEM IN DNA, AND TO SOLUTION AROUND PURIFY VIRUS AN AXIS AT HIGH PARTICLES SPEED. Magnetic Separation The process of separating mixtures by using magnets to attract magnetic materials.  Evaporation Separation by Evaporation  Evaporation is used for separating solid substance that has dissolved in walter Filtration What is filtration?  Isa method for separating insoluble solid from a liquid Decantation  Chromatography  It is a technique for separating mixtures into their constituent parts.  At its core, chromatography is the interaction between the mobile phase, which carries the mixture being separated, and a stationary phase which performs the separation.  Gas chromatography is used to help catch criminals by analyzing the blood and cloth samples.  Sieving  Sieving is used to separate those solid mixtures which have components of different sizes.  The larger particles can’t pass through the small holes of the sieve and remain behind the sieve  Other Separation Techniques Handpickin Threshing g
