C2H2 provides ideal gas thermodynamic and transport properties for acetylene over the temperature range from 200 K to 3500 K based on the property information from McBride et al. (2002).  The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25C.  The reference state for specific entropy is based on the Third Law of Thermodynamics.

The low density viscosity correlation is applicable (with an uncertainty of 3%) for 250 K< T < 750 K

The low density thermal conductivity correlation is applicable (with a 5% uncertainty) for 250 K < T < 750 K
