Data: ΔP (decrease in the weight of the taken iron bar) = 160 N = Fa (Archimedes force).
Constants: g (acceleration due to gravity) ≈ 10 m / s2; according to the condition ρс (alcohol density) = 800 kg / m3.
To find the volume of the taken iron bar, we apply the formula: Fa = ρс * g * V and V = Fa / (ρс * g).
Let’s calculate: V = 160 / (800 * 10) = 0.02 m3 or 20 dm3.
Answer: The taken iron bar has a volume of 20 dm3.
