9. from the densities below, decide whether each substance will sink or float in sea water. sea water
has a density of 1.025 g/ml. (write sink or float on the line.)
gasoline 0.66 g/ml
asphalt 1.2 g/ml
cork 0.26 g/ml

Gasoline will float

Asphalt will sink

Cork will float

Explanation:

Simply compare the value of each object's density to that of the sea water (1.025 g/ml). If the density of the object is less than that of the water, the object will float due to the buoyance force.

Contrarily, if the density of the object is larger than that of sea water, the object will sink.

Gasoline, with density 0.66 g/ml which is less than that of sea water, will float.

Gasoline, with density 1.2 g/ml which is more than that of sea water, will sink.

Cork, with density 0.26 g/ml which is less than that of sea water, will float.
