The ___ of oil causes the oil to float in water. Less than 1.0 sg

Explanation:
Buoyancy is determined by how dense a liquid is compared with the surrounding water. Specific gravity expresses that comparison as a ratio to water’s density, so SG = density(oil) / density(water). Since oil is less dense than water, its SG is below 1.0, meaning it will rise and float on water. Viscosity affects how thick a liquid flows, not whether it floats; boiling point relates to vaporization, not buoyancy. The key idea here is that the oil’s relative density to water is what decides its position on the water surface, and that is captured by its specific gravity.
