Science / Chemistry / Ideal Gas: A gas whose pressure P, volume V, and temperature T are related by PV = nrt, where n is the number of moles of gas and R is the ideal gas law constant. Ideal gases have molecules with negligible size, and the average molar kinetic energy of an ideal gas depends only on its temperature. Most gases behave ideally at sufficiently low pressures.
Ideal Noun Synonyms: model, paragon, standard, criterion, paradigm, exemplar, pattern, example, epitome
Science / Chemistry / Ideal Gas Law Constant: A constant R equal to PV/(nt) for ideal gases, where the pressure, volume, moles, and temperature of the gas are P, V, n, and T, respectively. The value and units of R depend on the units of P, V, and MORE
