The Kelvin scale temperature is 0 K. What is the corresponding Celsius scale temperature ?

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true and reason is not the correct explanation of assertion.
C. If assertion is true and reason is false.
D. If both assertion and reason are false.

Answer

To find the corresponding Celsius scale temperature for a given Kelvin scale temperature of 0 K, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Temperature in Kelvin**:
- We are given a temperature of 0 K.

2. **Recall the Conversion Formula**:
- The relationship between Kelvin (K) and Celsius (°C) is given by the formula:
\[ T(K) = T(°C) + 273 \]
- To convert from Kelvin to Celsius, we rearrange this formula:
\[ T(°C) = T(K) - 273 \]

3. **Substitute the Given Temperature into the Formula**:
- Now, substitute 0 K into the rearranged formula:
\[ T(°C) = 0 K - 273 \]

4. **Calculate the Celsius Temperature**:
- Perform the subtraction:
\[ T(°C) = -273 \]

5. **State the Final Answer**:
- The corresponding Celsius scale temperature for 0 K is:
\[ -273 °C \]

### Final Answer:
The corresponding Celsius scale temperature for 0 K is **-273 °C**.
