Coexistence Curve and Parametric Equation of State for 4He Near Its Critical Point

  • Henry A. Kierstead

Abstract

Recent advances in the theory of critical phenomena have emphasized the need for high-quality experimental data and, through the scaling law, have provided a means for analyzing the data in a simple fashion. Available data on the thermodynamic properties of 4He fall short of satisfying this need. Therefore we have measured the pressure coefficient (∂ P/ T) ρ along 29 isochores in the density range − 0.2 < Δρ < 0.2 and the temperature range − 0.02 < t < 0.032, where Δρ = (ρ - ρ c )/ρ c and t = (T - T c )/T c .
