Properties of Matter Physical and Chemical

Properties of matter Physical Properties - characteristic or description of the substance that may help to identify it Chemical Properties - characteristic behaviours that occurs when one substance reacts with another to form new substances.

Describe this liquid!

Qualitative Quantitative properties that can be measured properties that are observed and not measured with a numerical result Quantitative properties that can be measured

State of Matter Solid, Liquid, Gas, (Plasma) Solar plasmas of Jupiter

Solubility The ability of a substance to dissolve in a solvent Example: Sugar is soluble in water

Hardness Resistance of a solid to being scratched or dented Example: diamond is harder than glass Glass tiles are cut using water and diamond encrusted blades

Malleability Ability of a metal to be hammered or bent into different shapes Example: Aluminum foil is easily bent Chromium metal bent into different shapes

Describe the state, hardness and malleability of Playdoh.

Which substance is malleable. Which substance is harder Which substance is malleable? Which substance is harder? Which one has a lower melting point? Diamonds Copper Pipes

Chemical Properties of Matter Chemical Properties of Matter The ability of a substance to react with another substance and form one or more new substances

Corrosion A slow chemical change that occurs when metal reacts with oxygen to form oxides. For example, iron reacts with oxygen to form iron oxide. This is also called rusting or tarnishing.

Reactivity with Acids Substances react with acids to produce a gas. Example: baking soda and vinegar react to produce carbon dioxide gas

Combustibility The ability of a substance to react with oxygen to produce carbon dioxide. For example, when gas is brought close to a flame, it ignites and burns forming new substances.

Ductility Ability of a metal to be pulled into wires Example: Copper is very ductile and is commonly used for electrical wiring

Conductivity If a substance is able to conduct heat or electricity. Conductor – able to conduct Example: most metals, copper is very good Insulator – has little or no conductivity Example: styrofoam, glass

Melting and Boiling Points Temperature at which substances change state Water changes from solid to a liquid at 0ºC

Lustre - Shininess or dullness

Clarity Ability to allow light through Transparent, translucent or opaque

Viscosity How easy a liquid flows Example: The thicker the liquid, the slower it flows and is more viscous. Corn syrup is viscous, water is not viscous

Density The amount of matter per unit volume Density = mass/volume Example: Lead is very dense, feathers are not dense
