Chapter 3, Problem 65A

Interpretation Introduction

Interpretation : The relationship between degrees Celsius and kelvins is to be identified.

Concept Introduction : Temperature is the measure of an object’s heat or cold.

Answer to Problem 65A

The relationship between degrees Celsius and kelvins is given as:

  $\begin{array}{c}{}^{\circ }\text{C}\text{=}\text{K}-\text{273}\text{.15}\\ \text{K}\text{=}{}^{\circ }\text{C}+273.15\end{array}$

Explanation of Solution

A measure of an object's heat or cold is its temperature. The temperature of an object determines how heat is transferred. Heat is transferred from an object with a higher temperature to an object with a lower temperature when they are in contact.

The degree Celsius and the kelvin are two regularly used equivalent units of temperature by scientists.

The freezing point of water is $0^{\circ }\text{C}$ , and the boiling point is ${100}^{\circ }\text{C}$ . Each of these two fixed positions is separated by 100 equal increments, or degrees Celsius, in distance.

Another temperature scale used in physical science is the Kelvin or absolute scale.

Water has a freezing point of 273.15 K and a boiling point of 373.15 K on the Kelvin scale. The degree symbol is not utilized while using the kelvin scale.

The relationship between degrees Celsius and kelvins is given as:

  $\begin{array}{c}{}^{\circ }\text{C}\text{=}\text{K}-\text{273}\text{.15}\\ \text{K}\text{=}{}^{\circ }\text{C}+273.15\end{array}$
