<ol>
<li>The volume of a sample of a gas at 273C is 200L. If the volume is decreased to 100L at constant pressure, what will be the new temperature of the gas?</li>
</ol>

<p>I got 273K (or 0C)</p>

<ol>
<li>What will be the new volume of 100mL of gas if the Kelvin temperature and the pressure are both doubled?</li>
</ol>

<p>I got 100mL, which seems too easy, but logical since I'm using the combined formula (which combines a direct and indirect relationship). </p>

<p>I can't find the answer key to these problems. Thanks in advance!</p>

<p>Both of those are right…You just need to use the combined gas law P1V1/T1=P2V2/T2…pretty straight forward.</p>

<p>^Thanks home boy!</p>

<p>EDIT: I hope you know that I did not just say that because you are from Kenya.</p>
