Pressure

Step 1: Formula for pressure at the bottom of a liquid column
The pressure at the bottom of a liquid column is given by the hydrostatic pressure formula: where: - is the atmospheric pressure (same for all vessels), - is the density of the liquid, - is the acceleration due to gravity, - is the height of the liquid column. Since all vessels are filled to the same height and are open to the atmosphere, the pressure difference at the bottom of each vessel is:

Step 2: Compare pressures for different liquids
Since , it follows that:

Step 3: Determine which vessel has a maximum pressure
From the relation , it is clear that the vessel containing liquid A has the maximum pressure at the bottom. Thus, the correct answer is that the pressure is

maximum in the vessel containing liquid A.
