You are presented with the question "This determines whether an object will sink or float:" and the following answer choices: 
- density
 - displacement
 - energy
 - sun's heat
 - phase
 - heat
 - swim
 - forces

Now knowing that if an object in a fluid is more dense than that fluid then that object will sink in that fluid because of gravity and specific gravity is related to density, choose the best answer.


 

 density
