Students will: Describe changes in particle bonding during changes of state. Differentiate between latent heat of fusion and latent heat of vaporization. Perform calculations involving specific latent heat. Starter Activity: Define key terms: specific heat capacity, internal energy, temperature. Recall the formula for specific heat capacity. Identify various changes of state. Introduction to Concepts: Define latent heat as the energy required for a phase change without a temperature change, focusing on overcoming intermolecular forces. Differentiate between specific latent heat of fusion (solid ↔ liquid) and vaporization (liquid ↔ gas). Discuss the role of energy transfer during state changes (e.g., energy input during melting and boiling, energy release during freezing and condensation). Worked Examples and Practice: Solve problems such as calculating the energy required to change a specific mass of a substance’s state using the formula. Interactive Questions: Use mini whiteboards for multiple-choice questions on changes of state, energy transfers, and misconceptions (e.g., whether temperature changes during state changes). Recap key differences between specific heat capacity and latent heat. Assign calculations for practice, such as determining energy transfer for melting ice or boiling water. This lesson blends theory and practical calculations, preparing students for real-world applications of thermodynamic principles.
