Chapter 13, Problem 6P

To determine

(a) To determine:

The temperature on the Fahrenheit scale for the given Celsius temperature

Answer to Problem 6P

Solution:

$0.4°F$

Explanation of Solution

Given:

Temperature = $-18°C$

Formula used:

$T(°F)=\frac{9}{5}T(°C)+32$

Calculation:

The formula to convert temperature from Celsius scale to Fahrenheit scale is

$T(°F)=\frac{9}{5}T(°C)+32$

Substituting the value of $T\left(°C\right)$ here

$T(°F)=\frac{9}{5}(-18)+32=0.4°F$

To determine

(b) To determine:

The temperature on the Celsius scale for the given Fahrenheit temperature

Answer to Problem 6P

Solution:

$-27.8°C$

Explanation of Solution

Given:

Temperature = $-18°F$

Formula used:

$T(°C)=\frac{5}{9}[T(°F)-32]$

Calculation:

The formula to convert temperature from Fahrenheit scale to Celsius scale is

$T(°C)=\frac{5}{9}[T(°F)-32]$

Substituting the value of $T\left(°F\right)$ here

$T\left(°C\right)=\frac{5}{9}[-18-32]=-27.8°C$
