If a liquid has a specific gravity of less than 1, what will happen to it in water?

A liquid with a specific gravity of less than 1 will float on water because specific gravity is a measure of the density of a substance compared to the density of water. Water has a specific gravity of 1; therefore, when the specific gravity of another liquid is less than 1, it indicates that the liquid is less dense than water. Since less dense substances will rise to the surface when placed in a denser fluid, the liquid will float.

In contrast, options like sinking, dissolving, or evaporating do not accurately describe the behavior of a liquid with a specific gravity less than 1 in water. Sinking would occur if the liquid's specific gravity were greater than 1, and while some substances might dissolve or evaporate, these processes depend on chemical properties rather than gravitational density.
