Chapter 1, Problem 1.74P

Interpretation Introduction

(a)

Interpretation:

The highest air temperature in Antarctica that is $\text{17}\text{.5 }°\text{C}$ is to be calculated in Fahrenheit.

Concept introduction:

Kelvin $\left(\text{K}\right)$ is the S.I unit of temperature. One unit can be converted into another by the use of proper conversion factors.

The formula to convert temperature from degree Celsius to Kelvin is,

  $T\left(\text{K}\right)=T\left(\text{°C}\right)+273.15$   ........ (1)

The formula to convert temperature from degree Celsius to Fahrenheit is,

  $T\left(\text{°F}\right)=\frac{9}{5}T\left(°\text{C}\right)+32$ ...... (2)
