A liquid with specific gravity 0.8 will behave how on water?

Explanation:
Specific gravity compares a liquid’s density to water. Water has a gravity of 1.0, so anything lighter than water (SG less than 1) will float on the surface. A liquid with SG 0.8 is 20% lighter than water, so it will ride on top rather than sink. In a spill, expect a surface layer that can spread with wind and currents. This behavior is about density relative to water, not about chemical reactions or dissolution.
