Abstract: This paper explains the effect of surrounding gas pressure on splashing phenomena of liquid drop using fixed volume canonical ensemble of gas at high pressure and liquid. The energy state fluctuations in liquid drop energy (𝐸_𝐿) are given by exponential probability distribution at high pressures. High pressure increases the translational components of the kinetic energy which are not normal to the drop surface. This corresponds to higher range of incidence angles, which controls the impact outcome. Furthermore, Surface coverage of liquid molecules (𝜃_𝑙𝑖𝑞) by adsorption process is derived, which is the function of surrounding gas pressure 𝑝. High pressure decreases the surface coverage of liquid molecules making the liquid drop more vulnerable for splashing.
