In these systems, which tend to occur at high temperatures and low pressures, Gay-Lussac's and Boyle's Laws are true.
For an isothermal process, the change in entropy of one of these systems is proportional to the natural log of the ratio of final to initial pressure. In these systems, the internal energy and enthalpy are solely functions of temperature, and the heat capacity at constant pressure is equal to the heat capacity at constant volume plus R. These systems have a fugacity coefficient of 1, a compressibility factor of 1, zero intermolecular attractions and zero particle volume. In these systems, which tend to occur at high temperatures and low pressures, Gay-Lussac's and Boyle's Laws are true. For 10 points, name this theoretical phase of matter whose namesake law states that PV = nRT.
