`-273.15C` is

Options

A. `-0.15^(@)C`
B. `0 K`
C. `-0.15^(@)F`
D. `0^(@)F`

Answer

To solve the question regarding the temperature of -273.15°C, we need to convert it into Kelvin and Fahrenheit to find the correct answer.

### Step-by-Step Solution:

1. **Understanding the Temperature Scale**:
- The question provides a temperature in Celsius (-273.15°C) and asks for its equivalent in Kelvin and Fahrenheit.

2. **Convert Celsius to Kelvin**:
- The formula to convert Celsius to Kelvin is:
\[ K = C + 273.15 \]
- Substituting the given Celsius value:
\[ K = -273.15 + 273.15 = 0 \text{ K} \]

3. **Convert Celsius to Fahrenheit**:
- The formula to convert Celsius to Fahrenheit is:
\[ F = \left(C \times \frac{9}{5}\right) + 32 \]
- Substituting the given Celsius value:
\[ F = \left(-273.15 \times \frac{9}{5}\right) + 32 \]
- Calculating:
\[ F = \left(-491.67\right) + 32 = -459.67 \text{ °F} \]

4. **Identifying the Correct Option**:
- The converted values are:
- 0 Kelvin
- -459.67 Fahrenheit
- From the options provided:
- Option A: -1.5 °C (Incorrect)
- Option B: 0 Kelvin (Correct)
- Option C: -0.15 °F (Incorrect)
- Option D: 0 °F (Incorrect)

Thus, the correct answer is **Option B: 0 Kelvin**.
