The correct value of `0^(@)C` on the Kelvin scale is

Options

A. (a) `273.15K`
B. (b) `273.16K`
C. (c) `273K`
D. (d) `273.2K`

Answer

To find the correct value of 0 degrees Celsius on the Kelvin scale, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between Celsius and Kelvin**:
The formula to convert Celsius to Kelvin is:
\[ T(K) = T(°C) + 273.15 \]
where \( T(K) \) is the temperature in Kelvin and \( T(°C) \) is the temperature in Celsius.

2. **Substitute the given temperature**:
We need to find the value of 0 degrees Celsius in Kelvin. So, we substitute \( T(°C) = 0 \) into the formula:
\[ T(K) = 0 + 273.15 \]

3. **Calculate the temperature in Kelvin**:
Performing the addition gives:
\[ T(K) = 273.15 \]

4. **Identify the correct option**:
From the options provided:
- A) 273.15 Kelvin
- B) 273.16 Kelvin
- C) 273 Kelvin
- D) 273.2 Kelvin

The correct value we calculated is 273.15 Kelvin, which corresponds to option A.

### Final Answer:
The correct value of 0 degrees Celsius on the Kelvin scale is **273.15 Kelvin** (Option A).
