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.

It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event.These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star.he fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements. See periodic table (iron is number 26). See related link.
