Please ### Educational Resource: Understanding Heating Curves of Water**1. Heating Water from 0°C to 100°C (Section C → D)**- **Question:** What happens when you heat water from 0°C to 100°C? What is this added heat being used for?- **Answer:** When water is heated from 0°C to 100°C, the added heat increases the kinetic energy of the water molecules, raising the temperature until it reaches the boiling point. The energy is used to overcome intermolecular forces, increasing the temperature and causing the phase transition from solid (ice) to liquid (water).**2. Calculating Heat Use**- **Prompt:** Can you determine how much heat is used in this part of the heating curve?- **Explanation:** To calculate the heat used, apply the formula \( q = m \cdot c \cdot \Delta T \), where \( q \) is the heat absorbed, \( m \) is the mass, \( c \) is the specific heat capacity, and \( \Delta T \) is the change in temperature.**3. Molecular Representation at 100°C**- **Task:** Draw what the sample of water would look like on the molecular level at 100°C, the phase change.- **Guideline:** At 100°C, water is at its boiling point. Illustrate the molecules as closely packed in the liquid state with hydrogen bonds between them. During the phase change, molecules gain energy, breaking the bonds and beginning to form a gaseous state (steam).**4. Heating Water at 100°C (Section D → E)**- **Question:** What happens when you heat water at 100°C? What is this added heat being used for?- **Answer:** Once water reaches 100°C, additional heat does not increase the temperature but is used for the phase change from liquid to gas (vaporization). This energy is known as latent heat of vaporization.By understanding these concepts, students can grasp the principles of thermodynamics and phase changes in the context of heating water. This image represents a phase change diagram illustrating the heating process of water over time. It shows the relationship between temperature (in degrees Celsius) and time (in minutes) as ice is heated and transitions through various phases:1. **Segment A-B**: - **Heating Ice**: From point A to B, the graph shows the gradual increase in temperature from below 0°C to 0°C as ice is heated. This takes about 10 minutes.2. **Segment B-C**: - **Melting Ice**: From point B to C, the temperature remains constant at 0°C as the ice melts into water. This phase change process takes about 10 minutes.3. **Segment C-D**: - **Heating Liquid Water**: From point C to D, the temperature of the liquid water increases from 0°C to 100°C. This heating process takes approximately 25 minutes.4. **Segment D-E**: - **Vaporizing Water**: From point D to E, the temperature remains constant at 100°C as the water transitions from liquid to vapor (boiling). This phase change lasts for about 45 minutes.5. **Segment E-F**: - **Heating Steam**: From point E to F, the temperature of the steam increases past 100°C, reaching around 140°C in 10 minutes.This diagram highlights the energy required for phase changes (melting and boiling), where the temperature remains constant as heat energy is absorbed to change the phase.

The curve is a heating curve that shows how ice is converted into steam by continuously supplying…
