Surface tension at critical temperature

WebCritical temperature: T fus: Fusion (melting) point: T triple: Triple point temperature: ΔH trs: Enthalpy of phase transition: ΔS trs: Entropy of phase transition: Δ fus H: Enthalpy of … WebThe increase in temperature causes a corresponding decrease in cohesive intermolecular forces and this surface tension decreases. For example, the surface tension of water and air is 72.8 mN/m at 20°C, while the surface tension at 25°C is 72.0 mN/m. Figure 5 plots the surface tension of water and air for a range of temperatures from ref. [9].
