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. Given these facts, what decreases when the density of an object increases among the following options:
- support
 - heat
 - forces
 - air cools
 - heat energy
 - buoyancy
 - Pollution
 - dry and hot
