Enthalpy of ideal gas formula
Webwhere d is the number of degrees of freedom of a molecule in the system.Table 3.3 shows the molar heat capacities of some dilute ideal gases at room temperature. The heat capacities of real gases are somewhat higher than those predicted by the expressions of [latex]{C}_{V}[/latex] and [latex]{C}_{p}[/latex] given in Equation 3.10.This indicates that … An ideal gas is a theoretical gas composed of many randomly moving point particles that are not subject to interparticle interactions. The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics. The requirement of zero interaction can often be relaxed if, for example, the interaction is perfectly elastic or …
