<p>Hi there!
I have a chemistry question.</p>
<p>1.Of the following, the conditions under which the molar volume of gaseous helium is greatest are,
(A). 237K and 1atm
(B). 300K and 1atm
(C). 400K and 1atm
(D). 500K and 2atm
(E). 600K and 2atm</p>
<p>The combined gas law says that PV/T = k (where k is a constant). Therefore V = kT/P, so you’re looking to maximize the value T/P. I think your answer is C.</p>
<p>Boyles Law:
Pressure is invesely proportional to volume.</p>
<p>To maximize volume, you must minimize pressure.
Choose answer with lowest pressure: P = 1atm</p>
<p>Charles Law:</p>
<p>Volume is proportional to temperature.</p>
<p>To maximize volume, you must maximize temperature.
Choose answer with greatest temperature: T = 400K</p>
