In fluid statics, capillary pressure is the pressure between two immiscible fluids in a thin tube (see capillary), resulting from the interactions of forces between the fluids and solid walls of the tube.
The elements formed in these stages range from oxygen through to iron. During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced.In the supernova explosion, all of these elements are expelled out into space.he elements formed in these stages range from oxygen through to iron.

The material, mostly hydrogen and helium, is attracted by the white dwarf's gravity and accumulates under growing pressure and heat until nuclear fusion is ignited. Unlike a supernova, a nova is not blown apart by the explosion and gradually returns to its original brightness over a period of weeks to years. Because of their sudden appearance where no star had been previously visible, novae were long thought to be new stars.
