Chapter 1, Problem 5a
The temperature on the surface of the Sun is 5778 K. What is the temperature in degrees Fahrenheit? (LO 1.6) (a) 3344 °F

1
Start by converting the temperature from Kelvin to Celsius using the formula: \( T_{\text{C}} = T_{\text{K}} - 273.15 \).
Substitute the given temperature in Kelvin (5778 K) into the formula to find the temperature in Celsius.
Next, convert the temperature from Celsius to Fahrenheit using the formula: \( T_{\text{F}} = \frac{9}{5}T_{\text{C}} + 32 \).
Substitute the calculated Celsius temperature into the formula to find the temperature in Fahrenheit.
Compare the calculated Fahrenheit temperature with the given option (3344 °F) to verify if it matches.

The pH Scale
Kelvin to Fahrenheit Conversion
To convert a temperature from Kelvin to Fahrenheit, the formula used is: °F = (K - 273.15) × 9/5 + 32. This formula accounts for the differences in the zero points and scaling between the Kelvin and Fahrenheit systems, allowing for accurate temperature conversion.
