solution:
Charles saw that the volume of certain measure of a gas changes by VO /273.15 for every degree rise or fall in temperature.VO being the volume at 0°C.The volume at any temperature t°C
is given by
![\[Vt~\text{ }=\text{ }VO\left( 1\text{ }+\text{ }t{}^\circ C/273.15 \right)\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-f0cba9d960dad0b535c5bb4fa463a407_l3.png "Rendered by QuickLaTeX.com")
Presently ,if the temperature is lowered,it turns out to be certain that at
![\[\begin{array}{*{35}{l}} t\text{ }=\text{ }-\text{ }273.15{}^\circ C \\ ~ \\ Vt~\text{ }=\text{ }VO\left( 1+\text{ }\left( -\text{ }273.15/273.15 \right) \right) \\ ~ \\ =\text{ }VO~\text{ }=\text{ }\left( 1-1 \right)\text{ }=\text{ }0 \\ \end{array}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-35c2a9d57fe680160bc0d308d55944d7_l3.png "Rendered by QuickLaTeX.com")
What’s more, beneath
![\[t\text{ }=\text{ }-\text{ }273.15{}^\circ C\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-61e30851f3e5b97df2b9be5042dd34d0_l3.png "Rendered by QuickLaTeX.com")
, Vt becomes negative, which is absurd
Consequently the actually huge most reduced temperature is – 273.15°
