A 20 L vessel was filled with liquid. What kind of liquid can it be if its weight is 160N.

To find the type of liquid poured into the vessel used, we apply the formula: P = m * g = ρx * V * g, from where we express: ρx = P / (V * g).

Constants and variables: P – weight of the liquid (P = 160 N); V is the volume of the vessel (V = 20 l = 0.02 m3); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: ρx = P / (V * g) = 160 / (0.02 * 10) = 800 kg / m3.

Answer: The vessel is filled with oil (ρн = 800 kg / m3).
