Question
### Cooling Curve Analysis The graph displayed above represents the cooling curve of a solution where the temperature (measured in °C) is plotted against time (measured in seconds, s). #### Graph Description: - **X-axis:** Time (s), ranging from 0 to 80 seconds. - **Y-axis:** Temperature (°C), ranging from -4°C to 20°C. The graph shows how the temperature of the solution decreases over time: - Initially, the temperature starts at around 19°C. - As time progresses, the temperature decreases steadily until it reaches a point where it remains constant for a period before continuing to drop again. - This plateau indicates the freezing point of the solution, where the temperature remains constant despite the ongoing heat loss. #### Observations: - Between 30 and 50 seconds, the temperature remains relatively stable, hovering around 0°C, indicating the phase change from liquid to solid. #### Question: Using the cooling curve (shown above), identify the freezing temperature for the solution. 1. 2°C 2. 1°C 3. 0.5°C 4. -0.5°C 5. -3°C **Correct Answer:** -0.5°C The freezing temperature for the solution is observed at approximately -0.5°C, where the temperature stabilizes before continuing to decrease. #### Navigation: - **Previous Page:** Chapter 5 - Test 3 - **Next Page:** Chapter 5 - Test 5 - You are currently on page 6 of 14.
