Chapter 3.2, Problem 31LC

Interpretation Introduction

Interpretation : The temperature in kelvin is to be calculated.

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

  $\text{K}{\text{=}}^{\circ }\text{C}\text{+}\text{273}\text{.15}$

Answer to Problem 31LC

The temperature of the surgical instrument is heated at $443\text{K}$ .

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.

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

The relation between kelvin and Celsius is given as:

  $\text{K}{\text{=}}^{\circ }\text{C}\text{+}\text{273}\text{.15}$

The given surgical instrument is heated at ${170}^{\circ }\text{C}$ .

To calculate the surgical instrument heating in kelvin, substitute the values in the above formula.

  $\begin{array}{c}\text{K}{\text{=}}^{\circ }\text{C}\text{+}\text{273}\text{.15}\\ {\text{=170}}^{\circ }\text{C}+273.15\\ =443.15\text{K}\end{array}$

Thus, the surgical instrument is heated at $443.15\text{K}$ .
