Answer:
The liquid with the highest viscosity will reach the bottom last.
Step-by-step explanation:
Viscosity is the measurement of the liquid or resistance of fluids to flow and it therefore measures its internal friction, as the liquid with high viscosity has its molecular structure gives it a high internal friction when it is moving, so it moves slowly, but the liquid with a lower viscosity has its molecular structure gives it a low internal friction and its resistance to the surface which pass on it is being lower, so it flows faster on the surface.
