FOCUS QUESTION

What are the states of matter and how does matter change between them?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Matter exists as Solid.
  • Matter exists as Liquid.
  • Matter exists as Gas.
  • Matter is made of Particles.
  • Solid melts into Liquid.
  • Liquid freezes into Solid.
  • Liquid evaporates into Gas.
  • Gas condenses into Liquid.
  • Solid sublimes into Gas.

How to read this map

Read each connection between states as a change-of-state statement, and notice that adding or removing energy drives the change in each direction.

Learning objectives

  • Name the three common states of matter.
  • Match each change of state to the states it connects.
  • Explain the role of energy in changing state.
  • Relate particle arrangement to each state.
Review standard: Change-of-state names were checked against standard secondary-school science descriptions. Sources: OpenStax Chemistry 2e — States of Matter.
