Celsius scale divides two fixed points into

Options

A. 180 parts
B. 212 parts
C. 100 parts
D. 32 parts

Explanation

To answer the question "Celsius scale divides two fixed points into," we need to identify the two fixed points on the Celsius scale and understand how the scale is structured.

### Step-by-Step Solution:

1. **Identify the Fixed Points**:
The Celsius scale is based on two fixed points:
- The **ice point** (lower fixed point) which is defined as the temperature at which pure ice melts at standard atmospheric pressure (1 atm), and this temperature is **0 degrees Celsius**.
- The **steam point** (upper fixed point) which is defined as the temperature at which water boils at standard atmospheric pressure (1 atm), and this temperature is **100 degrees Celsius**.

2. **Understanding the Scale**:
The Celsius scale measures temperature by dividing the range between these two fixed points. The range is from 0 degrees Celsius (ice point) to 100 degrees Celsius (steam point).

3. **Division of the Scale**:
The Celsius scale divides the interval between the ice point and the steam point into **100 equal parts**. Each part represents one degree Celsius.

4. **Conclusion**:
Therefore, the Celsius scale divides the two fixed points (0 degrees Celsius and 100 degrees Celsius) into **100 parts**.

### Final Answer:
The Celsius scale divides the two fixed points into **100 parts**.
