Degrees Fahrenheit for the surface, and degrees Celsius for the upper air.

a) Kelvin
b) Celsius
c) Fahrenheit
d) Rankine

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.
