In this study, molecular dynamics simulation of a nanoscale argon bubble is performed to confirm the validity of Stokes-Einstein equation. The center of bubble is found to move randomly as well as Brownian motion of solid particle and its radius is evaluated by density profile. Negative pressure of liquid is supposed to keep the bubble because liquid density is lower than natural saturated liquid density. Moreover, Kelvin effect seems to decrease vapor density in the bubble.
