The pressure of a 12 cm high liquid column is 852 Pa. Determine the density of the liquid.

The solution of the problem:

To solve this problem, you need to remember the formula for finding the pressure of a liquid column, which looks like this:

p = ρ * g * h.

p is the pressure of the liquid column;

ρ is the density of the liquid;

g is the acceleration of gravity;

h is the height of the liquid column.

We transform the formula for finding the pressure of the liquid column to find the density of the liquid.

ρ = p / (g * h) = 852 / (0.12 * 10) = 710 kg / m ^ 3.

Answer: 710 kg / m ^ 3.
