The temperature on the surface of the Sun is 5778 K. What is the temperature in degrees Fahrenheit? (LO 1.6) (a) 3344 °F
검증된 단계별 안내1
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.
