About This Topic

Students will explore latent heat as the energy involved in phase changes (melting, boiling) without temperature change.

Key Questions

  1. Explain why temperature remains constant during a phase change despite continuous heat input.
  2. Compare the latent heat of fusion and latent heat of vaporization for a substance.
  3. Predict the total heat required to convert ice to steam, considering all phase changes.
