Physical Properties L.G: I can differentiate between the different physical and chemical properties that we use to describe matter. Matter is anything that has mass & volume (Takes up space). Everything is matter except energy (for example) electricity/lights Physical Properties: a characteristic/description that would help identify a substance (using 5 senses) PHYSICAL PROPERTY Color DESCRIPTION What color is it? Texture What does it feel like? Odour What does it smell like? Spicy, sweet, burnt, etc. Taste What does it taste like? Lustre How shiny is it? Clarity Hardness Malleability Ductility Melting and Boiling Points Crystal Form EXAMPLE Blue, red, yellow, black, white, etc. Rough, smooth, gritty, etc. Sweet, sour, salty, bitter Gold has lustre; concrete is dull Can you see through it? Transparent (clear), translucent, opaque. A substance’s ability to Diamond is harder than glass. resist being scratched. How well a substance Aluminum foil, gold, and tin can be pounded or are all malleable substances. rolled into sheets. Any solid that can be Copper wire. stretched into a long wire. The temperature at Water turns from solid to which substances liquid at 0 degrees = melting change state. point. The regular or irregular Salt crystals are tiny cubes. pattern in a solid. Solubility Viscosity Density The ability for a substance to dissolve in a liquid. The resistance of a fluid to flow. Amount of mass in a given volume of a substance. Salt dissolves in water and is therefore soluble. Pepper does not. Syrup has a high viscosity compared to water. Water is denser than oil but gold is denser than water. Chemical Properties: Describes the ability of a substance to change into a new substance or substances. Property Combustible Forms gas when heated Reacts with acid Reacts with water Emits heat/light Light Sensitivity Description Ability to react with oxygen to produce carbon dioxide and water When substance is heated, a gas is formed Ability to produce a chemical change when combined with acid substances Ability to produce a chemical change when combined with water When combined with another substance it produces light or heat Ability to be changed by the energy in light
