Question 1196308
.
At 300 K, the given amount of fluorine gas has a volume of 30.0 L . What will be the temperature if the gas 
occupies a volume of 25 L at constant pressure? 
~~~~~~~~~~~~~~~~~


<pre>
Use the Charles' law. It states that under constant pressure, an ideal gas' volume is proportional 
to its absolute temperature. The volume of a gas at constant pressure increases linearly with 
the absolute temperature of the gas. The formula he created was 

    {{{V[1]/T[1]}}} = {{{V[2]/T[2]}}},


where T denotes absolute temperature (in Kelvins).


In your case,  {{{30/300}}} = {{{25/T[2]}}}.


From the proportion,  {{{T[2]}}} = {{{(300*25)/30}}} = 250 K.    <U>ANSWER</U>
