Fact 1: If an object in a fluid is more dense than that fluid then that object will sink in that fluid because of gravity.

Fact 2: Specific gravity is related to density.

Given the two facts above, answer the question "This determines whether an object will sink or float:" with the following options: 
- density
 - displacement
 - energy
 - sun's heat
 - phase
 - heat
 - swim
 - forces
