Which liquid will have the least pressure on the bottom: alcohol 1cm high. or 1cm high mercury?

The hydrostatic pressure inside the liquid at any depth does not depend on the shape of the vessel in which the liquid is located, and is equal to the product of the density of the liquid, the acceleration of gravity and the depth at which the pressure is determined:
We have the same height of the liquid column, the acceleration of gravity is always the same, which means that the pressure on the bottom depends only on the density of the liquid, we will use the tabular data:
kerosene density – 800 kg / m3
mercury density – 13600 kgm3
Based on the density, kerosene will exert much less pressure on the bottom than mercury.
Answer: kerosene
