True weight = actual gravitational force between the object and the Earth = m g
apparent weight = net force acting downwards vertically when placed in a fluid
           =  true weight - buoyancy force acting on the object
              = true weight - loss of weight when immersed in a fluid
 The most useful example of this is the ship or boat floating on water.  The loss of weight is equal to the true weight and hence the ship has zero apparent weight and it floats.

A balloon flying in air,  apparent weight is less than zero, so it flies higher.
