# The two vessels are filled to the same level. Vessel A is filled with water, vessel B is filled with oil. Is the pressure on the bottom

**The two vessels are filled to the same level. Vessel A is filled with water, vessel B is filled with oil. Is the pressure on the bottom of the vessels the same? Will liquid flow from one vessel to another, why?**

The pressure with which the liquid presses on the bottom of the vessel is determined by the formula:

P = ro * g * h, where ro is the density of the liquid, h is the height of the liquid column.

According to the condition of the problem, both vessels are filled to the same level, that is, the height of the liquid columns is the same. Then, the pressure will be at the liquid with a higher density. Density of water: 1000 kg / m ^ 3. The density of the oil is 920 kg / m ^ 3. Since the vessel A is filled with water, it means that the pressure in the vessel A will be higher, and accordingly, due to the pressure difference, the water will flow into the vessel with oil.
