Question

Одинаково ли давление разных жидкостей на дно одинаковых мензурок

Answer 1

Давление зависит от плотности жидкости, поэтому будет разным. 
Чем выше плотность , тем больше давление и наоборот. 

Answer 2

Do different liquids exert the same pressure on the bottom of identical measuring cylinders?

When it comes to the pressure exerted by different liquids on the bottom of identical measuring cylinders, it is important to consider the concept of hydrostatic pressure. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it.

According to Pascal's principle, the pressure exerted by a fluid is transmitted equally in all directions. This means that the pressure at the bottom of a measuring cylinder filled with a liquid will be the same regardless of the type of liquid used, as long as the height and density of the liquid are the same.

In other words, if you have two identical measuring cylinders filled with different liquids, but the height and density of the liquids are the same, the pressure exerted on the bottom of both cylinders will be equal.

It is important to note that this principle holds true only when the liquids are incompressible and the measurements are taken at the same level. If the liquids are compressible or the measurements are taken at different levels, the pressure exerted on the bottom of the measuring cylinders may vary.

In summary, different liquids will exert the same pressure on the bottom of identical measuring cylinders as long as the height and density of the liquids are the same.
