Transcribed Image Text:### Temperature versus Time Analysis
#### Graph Description
The graph displayed in the image is a cooling curve depicting the relationship between temperature (in degrees Celsius, °C) and time (in seconds, s).
- **Y-Axis (Vertical):** Represents the Temperature ranging from -2°C to 25°C.
- **X-Axis (Horizontal):** Represents the Time ranging from 0 to 40 seconds (s).
Individual data points are marked with blue diamonds, indicating the temperature recorded at each specific time interval.
#### Examination of Data Points:
- At time 0 seconds, the temperature is approximately 25°C.
- As time progresses, the temperature decreases.
- A notable plateau can be observed around the 10-second to 20-second range, where the temperature stabilizes at approximately 3°C.
- Post this period, the temperature continues to decline, reaching close to -1°C by the 35-second to 40-second range.
#### Key Observation:
- **Plateau Region:** The plateau observed in the temperature vs. time graph is indicative of the phase change where the substance is transitioning from liquid to solid. This is typically the freezing point of the solution.
#### Question:
Using the cooling curve (shown above), identify the freezing temperature for the solution.
1. 7°C
2. 3°C
3. 1.5°C
4. -1°C
Based on the plateau region in the cooling curve, the freezing temperature for the solution is approximately **3°C**.
#### Selected Answer:
- 3°C
