Question: What is the Fahrenheit temperature of a person with a39.0ºCfever

Short answer

Answer:

A person with a temperature of has the equal temperature as on the Fahrenheit scale.

Step-by-step solution

Difference between Fahrenheit and Celcius

You need to find the Celcius corresponding Fahrenheit temperature. So the relation between the two-scale is,

$$\begin{gathered} \mathrm{C}=\frac{5}{9}\left(\mathrm{F}-32\right) \\ \mathrm{C}\times \frac{9}{5}=\left(\mathrm{F}-32\right) \end{gathered}$$

Calculation

When T=, Substituting this into the above equation, we get,

$$\begin{gathered} \text{39.0}°\text{C}\times \frac{9}{5}=\left(\text{F}-\text{32}\right) \\ 70.2°\text{C}=\text{F}-\text{32} \\ \text{F}=102.2°\text{F} \end{gathered}$$

Therefore, a person with a temperature has the same temperature as a person with a temperature on the Fahrenheit scale. Thermometers are used to measure temperature on well-defined measurement scales. Different temperature scales can be developed by finding easily reproducible temperatures, such as freezing and boiling water at standard atmospheric pressure.
