Ideal Gas Law is an equation of state of a hypothetical Gas, namely the ideal Gas. An ideal gas is an assembly of volume-less hard atoms which do not attract or repel each other but can collide with each other elastically. This equation can be applied for real gases at high temperature or at low pressure.

It is because all the equations of thermodynamics (except ones which have ideal gas laws substituted in them) were experimentally confirmed under normal conditions. The enthalpy H is defined as H=U+PV, but for an ideal gas PV=nRT so, for an ideal gas, H=U+nRT. Since, for an ideal gas, U depends only on T then the entire right hand side of this equation depends only on T and thus H depends only on T - for an ideal gas only.

This final equation   In the above equation we have indicated that $ c_v$ can depend on $ T$ . Like the internal energy, the enthalpy is also only dependent on $ T$ for an ideal gas. 18 Jan 2009 Ideal Gas Enthalpy of Nitrogen (N2) Enthalpy of Formation: 0 (kJ/kmol) Molecular Weight: 28.013 (kg/kmol). Temp.

Whenever a chemical symbol notation (e.g., N2, CO2, CH4) is used, the substance is modeled as an ideal gas and the enthalpy and entropy values are based on JANAF table references. The JANAF table reference for enthalpy is based on the elements having a specific molar enthalpy value of 0 at 298 K (537 R).

Internal Energy and Enthalpy of An Ideal Gas The equations of state are usually written in terms of certain derivatives, called the specific heats. The "isochoric specific heat" or "specific heat at constant volume" is defined as c v = du/dT and the "isobaric specific heat" or "specific heat … For such a gas, the internal energy and enthalpy are linear functions of temperature. Note that other authors call perfect gas what we call an ideal gas. In this case, they must each time tell whether the heat capacity of gas depends or not on the temperature.
