Recently, the phenomenon of super conductivity has been observed at `95^(@)K`. This temperature is nearly equal to

Options

A. `-288^(@)F `
B. `-146^(@)F`
C. `-368^(@)C `
D. `+178^(@)C `

Explanation

To solve the problem of converting the temperature of superconductivity from Kelvin to Celsius and Fahrenheit, we will follow these steps:

### Step 1: Convert Kelvin to Celsius
We know the formula to convert Kelvin to Celsius:
\[ \text{Temperature in Celsius} = \text{Temperature in Kelvin} - 273 \]
Given:
\[ \text{Temperature in Kelvin} = 95 \, K \]
Substituting the value:
\[ \text{Temperature in Celsius} = 95 - 273 \]
Calculating this gives:
\[ \text{Temperature in Celsius} = -178 \, °C \]

### Step 2: Convert Celsius to Fahrenheit
Next, we will convert the temperature in Celsius to Fahrenheit using the formula:
\[ \text{Temperature in Fahrenheit} = \left( \frac{9}{5} \times \text{Temperature in Celsius} \right) + 32 \]
Substituting the Celsius value:
\[ \text{Temperature in Fahrenheit} = \left( \frac{9}{5} \times -178 \right) + 32 \]
Calculating this step-by-step:
1. Calculate \( \frac{9}{5} \times -178 \):
\[ \frac{9 \times -178}{5} = -320.4 \]
2. Now add 32:
\[ -320.4 + 32 = -288.4 \, °F \]

### Final Answers
- Temperature in Celsius: \( -178 \, °C \)
- Temperature in Fahrenheit: \( -288.4 \, °F \)

### Conclusion
The temperature of superconductivity observed at \( 95 \, K \) is approximately \( -178 \, °C \) and \( -288.4 \, °F \).
