Question

Use the formula F = 9/5 (K - 273.15) + 32 to convert 100 degrees Fahrenheit to kelvin K.

A) 310.93 K
B) 322.04 K
C) 286.48 K
D) 294.61 K

Answer 1

To convert 100 degrees Fahrenheit to Kelvin, subtract 32 from the Fahrenheit temperature, multiply this by 5/9, and add 273.15. The result is approximately 310.93 Kelvin.

Step-by-step explanation:

To convert 100 degrees Fahrenheit to Kelvin, we need to rearrange the given formula F = 9/5 (K - 273.15) + 32 to solve for K. This results in the formula K = 5/9 (F - 32) + 273.15. Let's apply the formula:

• First, subtract 32 from the Fahrenheit temperature: 100 - 32 = 68.
• Next, multiply this value by 5/9 to convert it to Celsius: 68 * 5/9 ≈ 37.78.
• Finally, add 273.15 to the Celsius temperature to convert it to Kelvin: 37.78 + 273.15 = 310.93.

Therefore, 100 degrees Fahrenheit is approximately 310.93 Kelvin (Option A).
