Surface Tension of Methane+Hexane System is the energy, or work, required to increase the surface area of a system (Methane+Hexane) due to intermolecular forces. And is denoted by γ(Methane+Hexane). Surface Tension of Methane+Hexane System is usually measured using the Newton per Meter for Surface Tension. Note that the value of Surface Tension of Methane+Hexane System is always positive.
