Answer :
Final answer:
To convert from Kelvin to Celsius, subtract 273.15 from Kelvin; then convert Celsius to Fahrenheit using the formula F = (C × 9/5) + 32. For the sun's surface, the conversion gives 5526.85°C or 9960.33°F; for gold's boiling point, it's 2806.85°C or 5084.33°F; for liquid nitrogen's boiling point, it's -195.79°C or -320.42°F. So the correct answer is Option B.
Explanation:
When converting from Kelvin to Celsius, you subtract 273.15 from the Kelvin temperature. For Fahrenheit, you first convert to Celsius and then use the equation F = (C × 9/5) + 32 to find the Fahrenheit temperature.
a. Temperature of the surface of the sun (5800 K):
- To convert to Celsius: 5800 K - 273.15 = 5526.85°C
- To convert to Fahrenheit: (5526.85 × 9/5) + 32 = 9960.33°F
b. Boiling point of gold (3080 K):
- To convert to Celsius: 3080 K - 273.15 = 2806.85°C
- To convert to Fahrenheit: (2806.85 × 9/5) + 32 = 5084.33°F
c. Boiling point of liquid nitrogen (77.36 K):
- To convert to Celsius: 77.36 K - 273.15 = -195.79°C
- To convert to Fahrenheit: (-195.79 × 9/5) + 32 = -320.42°F
The correct answer to the question stated at the beginning is (b) Celsius.
