Water and sunflower oil of equal weight were poured into two identical vessels

Water and sunflower oil of equal weight were poured into two identical vessels, respectively. Which of the liquids will take up the largest volume?

Provided the same mass of poured liquids, a larger volume should be occupied by a liquid with a lower density. Consequently, a larger volume should be occupied by sunflower oil, since ρpm (sunflower oil) = 930 kg / m3, and ρw (water) = 1000 kg / m3.

Proof: ρpm * Vpm = m (mass) = ρw * Vw, whence we express: Vpm / Vw = ρw / ρpm = 1000/930 = 1.075, that is, Vpm = 1.075Vv.

Answer: Sunflower oil will take a larger volume.
