Chapter 3, Problem 12STP

Interpretation Introduction

Interpretation : The statement I and II are true or false is to be decided and check whether statement II is the explanation for statement I.

Concept Introduction : Temperature is the measure of an object’s heat or cold. The relation between kelvin and Celsius is given as:

  ${}^{\circ }\text{C}\text{=}\text{K}-\text{273}$

Answer to Problem 12STP

The statement I is true.

Statement II is also true and it is the correct explanation for statement I.

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 relationship between degrees Celsius and kelvins is given as:

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

So, according to the relationship between Celsius and kelvin, statements I and II are true.

Kelvin is always numerically greater than Celsius.
