Chapter 5, Problem 45A

Interpretation Introduction

Interpretation: The number of degrees between the normal freezing and boiling of water on both the Celsius and Kelvin temperature scales needs to be determined.

Concept introduction: To convert one unit into another, first needs to choose a conversion factor. This cancels the units and omits the units in the result. The relationship between Kelvin and Celsius scale is as follows:

  $T_K=T_{°C}+273.15$

Answer to Problem 45A

There are 100 degrees between the normal freezing and boiling of water on both Celsius and Kelvin temperature scales

Explanation of Solution

In Kelvin scale, freezing point of water is 273K and normal boiling point is 373K. In Celsius scale normal freezing point is $0°\text{C}$ and normal boiling point is $100°\text{C}$ . Thus, in both Kelvin and Celsius scale, there are 100 degrees between normal freezing and boiling point.

Conclusion

In Kelvin and the Celsius scales, unit of temperature are Kelvin and degree Celsius respectively.

The relationship between Kelvin and Celsius scale is as follows:

  $T_K=T_{°C}+273.15$
