Presentation on theme: "Physical and Chemical Properties of Matter"— Presentation transcript:
1 Physical and Chemical Properties of Matter Objective: Students will classify matter by physical and chemical properties and identify changes in matter.
2 Matter is EVERYWHERE and is found in different forms as solids, liquids and gases.
3 When we examine a substance, we are interested in its properties When we examine a substance, we are interested in its properties. A property issomething about a substance that can help to define it.Properties can beboth physical andchemical.
4 Properties of matter are both PHYSICAL and CHEMICAL
5 PHYSICAL PROPERTIESPhysical properties are thing about matter that can be observed without changing the substance into a different substance. There are many different physical properties that can be observed.H2O
6 Examples of Physical Properties Color – GoldAuGOLDDensity g/cm3
7 PHYSICAL PROPERTIES:GOLDMetal- STATE (solid, liquid or gas)
9 GOLD PHYSICAL PROPERTIES: Malleable- Bendable-forms into thin sheet Conductivity- Conducts heat and electricityDuctile- stretched into wire
10 PHYSICAL PROPERTIES:Soluble: to dissolve(without fizzing or bubbling!)
11 Examples of Physical Changes Size changeShape change
12 Examples of Physical Changes State changeSolid liquid gas
13 When a physical change occurs, the chemical composition of that substance DOES NOT CHANGE? THE MATTER basicallySTAYS THE SAMEAuAuAu
14 Iron + Oxygen = Rust 4Fe + 3O2 = 2Fe2O3 CHEMICAL PROPERTIES Chemical properties are characteristics of a substance that are observed when it REACTS or changesto produce differentsubstances.Iron Oxygen = Rust4Fe O = 2Fe2O3
15 Examples of Chemical Properties Reaction to…….. WATEROXYGENCHEMICALS
18 Iron + Oxygen = Rust 4Fe + 3O2 = 2Fe2O3 When matter undergoes a CHEMICAL CHANGE the atoms in the original substance are rearranged and producenew substances thatare structurally differentthan the original matter.Iron Oxygen = Rust4Fe O = 2Fe2O3
19 FIZZING and BUBBLING Signs that matter is undergoing a chemical change:Giving off HEAT/SMOKEFIZZING and BUBBLING
