Final answer:
The formula to convert temperature from Kelvin to Fahrenheit is fv = 1.8 × (v - 273.15) + 32, which translates Kelvin directly into Fahrenheit.
Step-by-step explanation:
To write a formula for the temperature fv in degrees Fahrenheit in terms of the Kelvin temperature v, you first need to use the relationship between kelvin and Celsius and then convert Celsius to Fahrenheit. To convert from Kelvin (K) to Celsius (C), use the formula:
C = K - 273.15
Once you have the temperature in Celsius, you can convert it to Fahrenheit using the following formula:
F = 1.8 × C + 32
Combining these two steps into one formula to convert directly from Kelvin to Fahrenheit:
F = 1.8 × (K - 273.15) + 32
So, the formula for fv in terms of v (the Kelvin temperature) is:
fv = 1.8 × (v - 273.15) + 32
