Will a steel ring float in kerosene?

Not. The density of steel is 7.7 – 7.9 g / cm³, while the density of kerosene is only 0.78 – 0.85 g / cm³. Due to the fact that the density of steel is much higher than that of kerosene, the ring sinks. In cases where the density of the liquid exceeds the density of the body in it, the body floats up (as an example, we can cite a birch, the average density of which is 0.65 g / cm³ – when it gets into water, it floats up, because the density of water is much higher).
