You are presented with the question "What decreases when the density of an object increases?" and the following answer choices: 
- support
 - heat
 - forces
 - air cools
 - heat energy
 - buoyancy
 - Pollution
 - dry and hot

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 an object is buoyant when it is less dense than the fluid around it, choose the best answer.


 

      buoyancy
