Physics A First Course

Matter and Energy

Matter and EnergyTemperature, Energy, and Matter
• 7.1 The Nature of Matter
• 7.2 Temperature and the Phases of Matter
• 7.3 What is Heat?
• 7.4 Heat Transfer
element

atom

compound

molecule

mixture

Describe the nature of matter at the atomic level.

Explain how Brownian motion supports the theory that matter is made of tiny, invisible particles.

Distinguish between elements, compounds, and mixtures.
