Chapter L, Problem 1PS

Many laboratories use 25^°C as a standard temperature. What is this temperature in kelvins?

Interpretation Introduction

Interpretation: The temperature in kelvin has to be given.

Concept Introduction:

Conversion of Celsius to Kelvin:

The conversion of Celsius to Kelvin is done by adding $\text{°C}$ and $\text{273}\text{.15°C}$,

  $\text{°C+273}\text{.15°=K}$

Answer to Problem 1PS

The temperature in kelvin is $\text{298K}\text{.}$

Explanation of Solution

The temperature in kelvin is calculated as,

  $\begin{array}{l}\text{Given:}{\text{25}}^{\text{o}}\text{C}\\ {\text{1K= 1}}^{\text{o}}\text{C + 273 =}\text{273K}\\ \text{whereas,}\\ {\text{25}}^{\circ }\text{C}={25}^{\circ }\text{C + 273 = 298 K}\end{array}$

The temperature in kelvin is $\text{298K}$.

Conclusion

The temperature in kelvin was calculated as $\text{298K}\text{.}$
