Chapter 1.9, Problem 1.27P

(a)

Interpretation Introduction

Interpretation:

The temperature $\text{20}{\text{.}}^{\text{o}}\text{C}$ has to be converted to Fahrenheit.

Concept Introduction:

Temperature:  The measurement of hotness or coldness of an object is temperature.  The three temperature scales as,

1. 1) Celsius $\left({}^{\text{o}}\text{C}\right)$
2. 2) Kelvin $\left(\text{K}\right)$
3. 3) Fahrenheit $\left({}^{\text{o}}\text{F}\right)$

Celsius to Fahrenheit conversion:

Celsius can be converted to Fahrenheit using the formula,

  ${\text{T}}_{\text{F}}\text{=1}\text{.8}\left({\text{T}}_{\text{C}}\right)\text{+32}$

(b)

Interpretation Introduction

Interpretation:

The temperature ${\text{150}}^{\text{o}}\text{F}$ has to be converted to Celsius.

Concept Introduction:

Fahrenheit to Celsius conversion:

Fahrenheit can be converted to Celsius using the formula,

  ${\text{T}}_{\text{C}}\text{=}\frac{{\text{T}}_{\text{F}}\text{-32}}{\text{1}\text{.8}}$

(c)

Interpretation Introduction

Interpretation:

The temperature ${\text{75}}^{\text{o}}\text{C}$ has to be converted to Kelvin.

Concept Introduction:

Celsius to Kelvin conversion:

Celsius can be converted to kelvin using the formula,

  ${\text{T}}_{\text{K}}{\text{=T}}_{\text{C}}\text{+273}$
