Chemical & Physical

What is a Physical Property? A physical property is a characteristic of matter that can be observed and measured without changing the identity or chemical makeup of the substance.
What are some examples of Physical Property? Some examples of physical properties are color, odor, size, hardness, luster, phase of matter, mass, density, boiling point, melting point, solubility, and conductivity.
We can easily observe the _______ of a substance by looking at it. Color
Many substances have a noticeable _________. Odor
The _________ of a substance can be measured without altering the chemical makeup of the substance. Size
_________ is the measure of how difficult or easy it is to scratch a substance. Hardness
Describes how light is reflected off the surface of an object. (How shiny is the object?) Luster
Amount of Matter in an object.? Mass
Is the effect of gravity on the mass of an object? Weight
How tightly packed the atoms in an object are? Density
The boiling point is... ... the point at which a substance changes from a liquid to a gas.
The melting point is... ...the point at which a substance changes from a solid to a liquid.
The measure in which an object dissolves into another object. Solubility
The measure of a material’s ability to allow the transport of an electric charge. Electric Conductivity
A trait or behavior of a substance that gives it the ability or inability to undergo a chemical change. A Chemical Property
The ability a substance has to burn. Both Combustibility and flammability
A chemical reaction that produces heat and light. Combustion
The ability or strength of a substance to cause poisonous effects to living things. Toxicity
A change that happens without changing the chemical composition of a substance. No new substance is formed. The change is usually (but not always) reversible. A Physical Change
Occurs when a substance undergoes a change that creates a new substance with different chemical and physical properties than the original substance. The change is not reversible. A Chemical Change
How easily an atom has a chemical reaction with another element. Reactivity
What causes the odor when milk sours? When milk begins to ferment (break down), it smells bad because of the bacteria that is being formed. Chemicals with a sour odor are released by this bacteria.
What causes the bubbles in a chemical reaction? Some chemical reactions occur and cause a gas to form. The bubbles are the evidence of the gas fumes escaping.
What is a precipitate? It is an insoluble (can’t dissolve) solid that is formed when two liquids combine.
Examples of Physical Properties? Malleable, Metal, Nonmetal, Metalliod, Density, Mass, Phase, Ductile, Color, Specific Gravity, Magnetism, Ability to dissolve, Conductivity, Solubility, Luster, Hardness, Size, Boiling Point, Odor, Melting Point, and Luminescence.
Examples of Chemical Properties? Toxicity, Reactivity, Radioactive, Flammability, Combustibility, and Oxidation.
Examples of Physical Changes? Example of dissolving, Cutting, and changing phases.
Examples of Chemical Changes? Formation of compound, example of reacting, example of oxidation, and example of toxicity.
