For any gas whose internal energy depends on temperature only,
the relation between pressure p, molar volume v, and absolute
temperature T can be approximated by using the Ideal Gas law: ??=??
where R is the universal gas constant. If p is measured in
atmospheres, v in liters/mole, and T in Kelvin, then R=0.08205
????? ?????? ?.
However, for certain physical conditions (notably high T and/or
high p), gases may behave in a nonideal way. A more general
