Chapter 3.3, Problem 3.20QAP

Interpretation Introduction

(a)

Interpretation:

The temperature of hot water given in Fahrenheit as $145\text{F}$ should be converted into degrees Celsius $(\text{C}\text{)}$

Concept Introduction:

• Substances are composed of atoms and molecules which are in constant motion. This motion imparts kinetic energy which gives rise to the property of temperature.
• Temperature is expressed in units of degrees Celsius or Fahrenheit
• The equation that relates the two is given as:

  $\begin{array}{l}{\text{T}}_{\text{F}}\text{ = 1}{\text{.8(T}}_{\text{C}}\text{) + 32 -----(1)}\\ {\text{where: T}}_{\text{F}}\text{= temperature in Fahrenheit}\\ {\text{T}}_{\text{C}}\text{= temperature in Celsius}\end{array}$

Interpretation Introduction

(b)

Interpretation:

The body temperature given in Celsius as $20.6\text{C}$ should be converted into degrees Fahrenheit $(\text{F}\text{)}$
