Chapter 3.2, Problem 24LC

Interpretation Introduction

Interpretation : The temperature units used commonly by scientists are to be identified.

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

Answer to Problem 24LC

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

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. Almost every substance experience expansion and contraction as temperature changes.

Numerous temperature scales use various units.

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.

The freezing point of water is $273.15\text{ K}$ whereas the boiling point is $373.15\text{ K}$ on the Kelvin scale. The degree symbol is not utilized while using the kelvin scale.
