Chapter 1, Problem 1.20QP

(a)

Interpretation Introduction

Interpretation:

The following temperatures have to be converted into kelvin.

1. (i) ${\text{113}}^{\text{0}}\text{C}$
2. (ii) ${\text{37}}^{\text{0}}\text{C}$
3. (iii) ${\text{357}}^{\text{0}}\text{C}$

Concept introduction:

Degree Celsius can be converted to Kelvin by using the equation,

$\text{K}\text{=}\left(\text{°C+273}\text{.15°C}\right)\frac{\text{1K}}{\text{1°C}}$

(b)

Interpretation Introduction

Interpretation:

The following temperatures have to be converted into degree Celsius.

1. (i) $77K$
2. (ii) $4.2K$
3. (iii) $601K$

Concept introduction:

Temperature in Kelvin scale can be converted to degree Celsius by using the equation,

${}^{\text{o}}\text{C}\text{=}\left(\text{K-273}\text{.15°C}\right)$
