Capitolo 1, Problema 5b

The temperature on the surface of the Sun is 5778 K. What is the temperature in degrees Fahrenheit? (LO 1.6) (b) 3040 °F

Guida verificata passo dopo passo
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 Fahrenheit conversion formula.
Perform the arithmetic operations to find the temperature in degrees Fahrenheit.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Temperature Scales

Temperature can be measured in different scales, primarily Celsius, Kelvin, and Fahrenheit. The Kelvin scale is an absolute temperature scale used in scientific contexts, where 0 K is absolute zero. The Fahrenheit scale is commonly used in the United States, where water freezes at 32 °F and boils at 212 °F. Understanding how to convert between these scales is essential for solving temperature-related problems.

Conversion Formulas

To convert temperatures between Kelvin and Fahrenheit, specific formulas are used. The conversion from Kelvin (K) to Fahrenheit (°F) is given by the formula °F = (K - 273.15) × 9/5 + 32. This formula allows for the accurate transformation of temperature values from one scale to another, which is crucial for interpreting scientific data in familiar terms.
