Question 1137495
----
The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. 
----


{{{V=kT/P}}}-------using lower-case k as the variation constant



-----
cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters.
-----


{{{120=k*310/18}}}


{{{k=120*18/310}}}


{{{k=12*18/31}}}


{{{k=216/31}}}

-

{{{highlight(V=(216/31)(T/P))}}}



------
What is the pressure if the volume is decreased to 100 liters and the temperature is increased to 320 degrees K?
------


This questions asks for P, given certain values of V and T.
