Chapter U3.5, Problem 9E

(a)

Interpretation Introduction

Interpretation: The given temperature in Fahrenheit scale that is 95 ^oF needs to be converted into Kelvin scale.

Concept Introduction:

The Kelvin and degree Fahrenheit are scales of measuring temperature. The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

Here, K is Kelvin and ^oF is degree Fahrenheit.

Answer to Problem 9E

  $308.15\text{ K}$

Explanation of Solution

The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

The given temperature is 95 ^oF. It can be converted into Kelvin as follows:

  $\left(95°F -32\right)\times 5/9+273.15=x$

On solving,

  $x=308.15\text{ K}$

Thus, the temperature 95 ^oF is equal to 308.15 K.

(b)

Interpretation Introduction

Interpretation: The given temperature in Fahrenheit scale that is 350 ^oF needs to be converted into Kelvin scale.

Concept Introduction:

The Kelvin and degree Fahrenheit are scales of measuring temperature. The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

Here, K is Kelvin and ^oF is degree Fahrenheit.

Answer to Problem 9E

  $449.82\text{ K}$

Explanation of Solution

The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

The given temperature is 350 ^oF. It can be converted into Kelvin as follows:

  $\left(350°F -32\right)\times 5/9+273.15=x$

On solving,

  $x=449.82\text{ K}$

Thus, the temperature 350 ^oF is equal to 449.82 K.

(c)

Interpretation Introduction

Interpretation: The given temperature in Fahrenheit scale that is 5 ^oF needs to be converted into Kelvin scale.

Concept Introduction:

The Kelvin and degree Fahrenheit are scales of measuring temperature. The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

Here, K is Kelvin and ^oF is degree Fahrenheit.

Answer to Problem 9E

  $258.15\text{ K}$

Explanation of Solution

The relation between two scales is as follows:

  $\left(32°F -32\right)\times 5/9+273.15=273.15K$

The given temperature is 5 ^oF. It can be converted into Kelvin as follows:

  $\left(5°F -32\right)\times 5/9+273.15=x$

On solving

  $x=258.15\text{ K}$

Thus, the temperature 5 ^oF is equal to 258.15 K.
