Chapter 5, Problem 48A

(a)

Interpretation Introduction

Interpretation: The value $\text{275}\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $\text{275}\text{K}$ in Celsius is $2°\text{C}$ .

Explanation of Solution

Conversion of $\text{275}\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =275-273\\ =2\end{array}$

Hence, $\text{275}\text{K}$ in terms of Celsius temperature value is $2°\text{C}$ .

(b)

Interpretation Introduction

Interpretation: The value $445\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $445\text{K}$ in Celsius is $172°\text{C}$ .

Explanation of Solution

Conversion of $445\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =445-273\\ =172\end{array}$

Hence, $445\text{K}$ in terms of Celsius scale temperature value is $172°\text{C}$ .

(c)

Interpretation Introduction

Interpretation: The value $0\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $0\text{K}$ in Celsius is $-273°\text{C}$ .

Explanation of Solution

Conversion of $0\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =0-273\\ =-273\end{array}$

Hence, $0\text{K}$ in terms of Celsius temperature scale value is $-273°\text{C}$ .

(d)

Interpretation Introduction

Interpretation: The value $77\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $77\text{K}$ in Celsius is $-196°\text{C}$ .

Explanation of Solution

Conversion of $77\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =77-273\\ =-196\end{array}$

Hence, $77\text{K}$ in terms of Celsius temperature scale is $-196°\text{C}$ .

(e)

Interpretation Introduction

Interpretation: The value $\text{10000}\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $\text{10000}\text{K}$ in Celsius is $9727°\text{C}$ .

Explanation of Solution

Conversion of $\text{10000}\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =10000-273\\ =9727\end{array}$

Hence, $\text{275}\text{K}$ in terms of Kelvin temperature value is $9727°\text{C}$ .

(f)

Interpretation Introduction

Interpretation: The value $\text{2}\text{K}$ needs to be converted to Celsius scale.

Concept Introduction: To convert temperature from Kelvin to Celsius scale, subtract $273$ from the Kelvin temperature. The relationship between Kelvin and Celsius scale is as follows:

  $T_{°C}=T_{\text{K}}-273$

Answer to Problem 48A

Converted value of $\text{2}\text{K}$ in Celsius is $-271°\text{C}$ .

Explanation of Solution

Conversion of $\text{2}\text{K}$ to Celsius is as follows:

  $\begin{array}{c}{T}_{°C}=T_{\text{K}}-273\\ =2-273\\ =-271\end{array}$

Hence, $\text{2}\text{K}$ in terms of Celsius temperature scale is $-271$ .
