The upward force that is exerted by a fluid against a submerging object is called as the Upthrust. It is defined as the loss of weight of the object when in water compared to its weight in air.
Upthrust is usually dependent on the density of the liquid and the volume of the body. A change in these quantities can vary the upthrust.
The apparent weight of the body may vary due to the upthrust. If the upthrust is equivalent to the weight of the object, then the object will float on the surface of the liquid.
However, when an object which is partially immersed is pressed down, there will be an increase in the upthrust.
