The law named for these substances is not effective when dealing with high pressures or low temperatures.
One problem concerning the substances is solved using the Sackur-Tetrode equation and is presented in the Gibbs paradox. The law named for these substances is not effective when dealing with high pressures or low temperatures. That law is a combination of laws named for Charles and Boyle. These substances are assumed to have no attractions between themselves, and have completely elastic collisions. For 10 points, name this hypothetical form of a phase of matter, which is modeled by its same named equation of PV=nRT ("P-V equals N-R-T").
