Also, the temperature in degree Fahrenheit can be converted into degree Celsius as follows:

$32{}^{\circ }\text{F=}\left({\text{0 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$.

Answer to Problem 154AP

$23{}^{\circ }\text{F}$.

Explanation of Solution

To convert the given temperature from degree Celsius to degree Fahrenheit, following formula is used

$32{}^{\circ }\text{F=}\left({\text{0 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$

Thus, for $-5{}^{\circ }\text{C}$, the temperature in Kelvin will be:

$23{}^{\circ }\text{F=}\left(-{\text{5 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$

Thus, tempreture in degree Fehrenheit will be $23{}^{\circ }\text{F}$.

Interpretation Introduction

(c)

Interpretation:

The following conversion should be performed.

$-196{}^{\circ }{\text{C to}}^{\circ }\text{F}$

Concept Introduction:

The temperature can be measured in three units; Kelvin, Degree Celsius and Degree Fahrenheit.

The temperature in degree Celsius can be converted into Kelvin as follows:

$0{}^{\circ }\text{C}=\text{273}\text{.15 K}$

Also, the temperature in degree Fahrenheit can be converted into degree Celsius as follows:

$32{}^{\circ }\text{F=}\left({\text{0 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$.

Answer to Problem 154AP

$-320.8{}^{\circ }\text{F}$.

Explanation of Solution

The temperature in degree Celsius can be converted into Fahrenheit as follows:

$0{}^{\circ }\text{C}=32{}^{\circ }\text{F}\left(\frac{5}{9}\right)-32$

Thus, for $-196{}^{\circ }\text{C}$, the temperature in Fahrenheit will be:

. $-196{}^{\circ }\text{C}=-320.8{}^{\circ }\text{F}\left(\frac{5}{9}\right)-32$

Therefore, $-196{}^{\circ }\text{C}$ is equal to $-320.8{}^{\circ }\text{F}$.

Interpretation Introduction

(d)

Interpretation:

The following conversion should be performed.

$\text{0 K to Fahrenheit degrees}$

Concept Introduction:

The temperature can be measured in three units; Kelvin, Degree Celsius and Degree Fahrenheit.

The temperature in degree Celsius can be converted into Kelvin as follows:

$0{}^{\circ }\text{C}=\text{273}\text{.15 K}$

Also, the temperature in degree Fahrenheit can be converted into degree Celsius as follows:

$32{}^{\circ }\text{F=}\left({\text{0 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$.

Answer to Problem 154AP

$-459.67{}^{\circ }\text{F}$.

Explanation of Solution

To convert the temperature into degree Celsius following formula is used. into degree Fahrenheit the following formula is used: Fist convert it into degree Celsius.

$0{}^{\circ }\text{C}=\text{273}\text{.15 K}$

Thus, $0\text{ K}=-\text{273}{\text{.15 }}^{\circ }\text{C}$

Now, temperture in degree Fahrenheit can be calculated as follows:

$-459.67{}^{\circ }\text{F=}\left(\text{-273}{\text{.15 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$

Therefore, $0\text{ K}$ is equal to $-459.67{}^{\circ }\text{F}$.

Interpretation Introduction

(e)

Interpretation:

The following conversion should be performed.

${\text{86 }}^{\circ }\text{C to Fahrenheit degrees}$

Concept Introduction:

The temperature can be measured in three units; Kelvin, Degree Celsius and Degree Fahrenheit.

The temperature in degree Celsius can be converted into Kelvin as follows:

$0{}^{\circ }\text{C}=\text{273}\text{.15 K}$

Also, the temperature in degree Fahrenheit can be converted into degree Celsius as follows:

$32{}^{\circ }\text{F=}\left({\text{0 }}^{\circ }\text{C}\left(\frac{9}{5}\right)\right)+32$.

Answer to Problem 154AP

$186.8{}^{\circ }\text{F}$.

Explanation of Solution

The temperature in degree Celsius can be converted into Fahrenheit as follows:

$0{}^{\circ }\text{C}=32{}^{\circ }\text{F}\left(\frac{5}{9}\right)-32$

Thus, for $86{}^{\circ }\text{C}$, the temperature in Fahrenheit will be:
