Changes of phase

This resource explores the concept of phase changes and latent heat, focusing on how particle behavior changes during transitions at constant temperature. Key learning objectives include the ability to identify phase changes on heating curves, understanding the constancy of temperature during these transitions, and applying the latent heat formula (Q = mL) to calculate thermal energy transfers. The document introduces essential vocabulary in both English and Chinese, provides visual overviews of energy and phase transitions, and includes guided practices with real-life applications. Students will learn to calculate the energy required for various phase changes, such as melting and vaporization, using specific latent heat values. A section dedicated to error analysis allows students to reflect on common mistakes in calculations. The resource encourages real-world connections by examining applications, such as cooking, and concludes with self-assessment and retrieval practices to gauge understanding.
