Temperature ConversionThe function CF=59F-32

converts a temperature in degrees Fahrenheit, F, to a temperature in degrees Celsius, C. The function K(C)=C+273converts a temperature in degrees Celsius to a temperature in kelvins, K.

(a) Find a function that converts a temperature in degrees Fahrenheit to a temperature in kelvins.

(b) Determine 80 degrees Fahrenheit in kelvins.

Short Answer

Expert verified

(a)K鈭�C=5F+22979

(b)K80=299.67

Step by step solution

01

Step 1. Given Information

The function CF=59F-32and KC=C+273

We need to find a function that converts a temperature in degrees Fahrenheit to a temperature in kelvins.

02

Part (a) Step 1. Finding a function converts a temperature in degrees Fahrenheit to a temperature in kelvins

K鈭�C=KCF=K59F-32K鈭�C=59F-32+273K鈭�C=59F-1609+273K鈭�C=59F-1609+24579K鈭�C=59F+22979K鈭�C=5F+22979

03

Part (b) Step 1. Determine 80 degrees Fahrenheit in Kelvins

KF=59F-32+273K80=5980-32+273K80=5948+273K80=299.67
