Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

**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
