Studies on sodium dodecylsulfate in aqueous and in aqueous amino acid solutions: Volumetric and viscometric approaches

The apparent molar volumes, ϕv of glycine in water are positive and increase with increasing temperature. The positive values of ϕv indicate that the solute-solvent interaction decreases as temperature increases (T = ◊, 293.15; ○, 298.15; Δ, 303.15; ♦ 308.15; □ 313.15 K).
