**Educational Website Transcript** --- **Title: Understanding Heating Curves for Water (H₂O)** **Introduction:** Explore the process of heating water from a solid state at -20°C to a vapor state at 125°C. This section will explain the heating curve, detailing the energy changes at different stages and helping students understand the formulas involved in calculating heat. **Data Table for Water (H₂O):** - **Melting Point:** 0.0°C - **Boiling Point:** 100.0°C - **Heat of Fusion:** 334 J/g - **Heat of Vaporization:** 2260 J/g - **Specific Heat Capacity (Solid):** 2.05 J/g°C - **Specific Heat Capacity (Liquid):** 4.18 J/g°C - **Specific Heat Capacity (Vapor):** 1.90 J/g°C **Heating Curve Explanation:** 1. **Graph Overview:** - This graph plots temperature (°C) against time, showing the change in state of water from -20°C to 125°C. - Important points are labeled from F to A. 2. **Stages of the Heating Curve:** - **F to E:** Heating of solid ice from -20°C to 0°C. - Formula: \( q = ms_s\Delta T \) - **E to D:** Melting of ice at 0°C to form liquid water. - Formula: \( q = m\Delta H_{\text{fus}} \) (Heat of Fusion) - **D to C:** Heating of liquid water from 0°C to 100°C. - Formula: \( q = ms_l\Delta T \) - **C to B:** Boiling of water at 100°C to form vapor. - Formula: \( q = m\Delta H_{\text{vap}} \) (Heat of Vaporization) - **B to A:** Heating of vapor from 100°C to 125°C. - Formula: \( q = ms_v\Delta T \) **Additional Information:** - **Variables Explained:** - \( q \): Heat energy - \( m \): Mass of the substance - \( s_s, s_l, s_v \): Specific heat capacities (solid, liquid, vapor) - \( \Delta T \): Change in
