Physical Properties of Substances

Properties of Matter

Every pure substance (element or compound) has a specific set of properties, either physical or chemical

Multiple Choice

Matter that is made of one type of molecule and has specific properties is known as

• A mixture

• A substance

• A homogenous

Multiple Choice

Which state of matter does NOT have a definite size or shape?

• Solid

• Liquid

• Gas

Multiple Choice

The ability to change shape is known as

• Conductivity

• Magnetivity

• Malleability

Physical Properties

• Physical Properties can be observed without changing the substance into another substance

Examples of Physical Properties

• color

• state of matter

• density (mass per volume)

• freezing point (temperature at which a substance freezes)

• solubility (ability to dissolve)

• malleability (how easily a metal can be manipulated)

Chemical Properties

• Describes a substances ability to change into a different substance

• In other words, the ability or inability of a substance to react with another substance

• These properties can only be observed when a substance undergoes a chemical change

• Ex/ sodium has the ability to react with water, gold does not react with water
