GCSE Internal Energy

This PowerPoint presentation provides a comprehensive lesson on internal energy for science students. It begins with an engaging starter activity to review foundational concepts such as specific heat capacity, energy transfer mechanisms, and kinetic energy stores. Key learning objectives include:

• Defining internal energy as the sum of kinetic and potential energy of particles in a substance.
• Exploring how heating affects a substance’s internal energy, temperature, and state of matter.
• Differentiating between changes in kinetic energy and potential energy during state changes like melting, boiling, and freezing.
• Understanding particle arrangements and movements in solids, liquids, and gases.
  The presentation also includes interactive tasks like gap-fill exercises, diagrams, and detailed explanations of heating curves. Practice questions reinforce understanding and encourage critical thinking about energy transfer and particle behavior during heating and phase transitions.
