How do we describe substances? • By using their physical and chemical properties • We describe substances by talking about the specific physical or chemical properties that they have.
What is a physical property? • A property that can be described using the five senses. • See, smell, taste, touch, hear • Observing the physical properties does not change or damage the substance to learn about it. We use our sense to observe the properties, we DO NOT change the substance. • Ex: Mass, density, color, size, texture etc.
What is a chemical property? • Describes a substances ability to react with other substances • We must change the identity of a substance to observe the chemical properties. • These changes are almost always irreversible • Ex: Combustion, Acidity, Rusting
