A nurse measures the temperature of a patient to be 40.7°C
(a) What is this temperature on the Fahrenheit scale?
°F
(b) Do you think the patient is seriously ill? (Assume the patient has a serious fever if the temperature is above 100°F.)
Yes
No
Explain
In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula.
F = 1.8C + 32
Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula.
K = C + 273.15
(a) Calculate that value.K(25) =
(b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins.
C =
(c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins.
F =
(d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?
Which of the following formulas relating temperatures on the Celsius and Fahrenheit scales is correct?
O TC = (TF +32°)/1.8
O TC = 1.8/(TF +32°)
TC = 1.8/(TF - 32°)
O TC = (TF - 32°)/1.8
