Q

You arrive on the scene of a vehicle accident involving a cargo tank truck carrying gasoline. The truck is leaking its product into a small lake. The driver of the truck gives you an MSDS sheet on gasoline, which gives a specific gravity of 0.8. With this information you can predict that the product will:
A - remain on top of the water, as it is lighter than the water.
B - sink to the bottom, as it is heavier than water.
C - completely mix with the water and no longer be a hazard.
D - react violently upon contact with the water.

A

A - remain on top of the water, as it is lighter than the water.
