What is approximately the pressure of alcohol in a bottle at a depth of 20 cm? density of alcohol 800 kg / m3.

Initial data: h (height of alcohol in a bottle) = 20 cm = 0.2 m.
Constants: g (acceleration of gravity) = 10 m / s2; by the condition ρс (alcohol density) = 800 kg / m3.
The pressure of alcohol in a bottle at a depth of 20 cm can be determined by the formula: Р = ρс * g * h.
Let’s calculate: P = 800 * 10 * 0.2 = 1600 Pa or 1.6 kPa.
Answer: The pressure of alcohol in the bottle at a depth of 20 cm is 1.6 kPa.
