What does buoyancy refer to? The expansion of objects In water The pressure a fluid exerts on an object The downward force that sinks objects in a fluid The downward force that sinks objects in a fluid The force that makes things float in a fluid

Buoyancy refers to the upward force that makes objects float in a fluid. This force is equal to the weight of the fluid displaced by the object. The pressure a fluid exerts on an object is related to buoyancy, but it is not the same thing. The downward force that sinks objects in a fluid is the weight of the object, which is counteracted by the buoyant force.
