Chapter 3.2, Problem 19SP

Interpretation Introduction

Interpretation : The temperature in kelvin is to be expressed.

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 19SP

The silver melts at $1233.95\text{K}$ and boils at $2485.15\text{K}$ .

Explanation of Solution

A measure of an object's heat or cold is its temperature.

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 element silver melts at ${960.8}^{\circ }\text{C}$ and boils at ${2485}^{\circ }\text{C}$ .

To calculate the melting of silver in kelvin, substitute the values in the above formula.

  $\begin{array}{c}\text{K}{\text{=}}^{\circ }\text{C}\text{+}\text{273}\text{.15}\\ \text{=}{960.8}^{\circ }\text{C}+273.15\\ =1233.95\text{K}\end{array}$

The silver melts at $1233.8\text{K}$ .

To calculate the boiling of silver in kelvin, substitute the values in the above formula.

  $\begin{array}{c}\text{K}{\text{=}}^{\circ }\text{C}\text{+}\text{273}\text{.15}\\ {\text{=2212}}^{\circ }\text{C}+273.15\\ =2485.15\text{K}\end{array}$

The silver boils at $2485.15\text{K}$ .
