When a white dwarf exceeds the Chandrasekhar limit what happens?
When a white dwarf exceeds the Chandrasekhar limit of about 1.4 times the mass of the Sun, electron degeneracy pressure is no longer able to support the star against gravity. This leads to the collapse of the white dwarf, resulting in a supernova explosion.
What happens during a supernova?
If the mass of the dead star is high enough, gravity will overcome electron degeneracy pressure holding the dead star up. Electrons will fall from their ground state into the nuclei, turning protons into neutrons and all the nuclei will merge forming a neutron star held up by neutron degeneracy pressure. If it stops here, the infalling outer layers that have not yet become neutrons crash into the super hard surface of the neutron star initiating a shockwave that propagates outward. This outgoing shockwave creates the supernova.If the mass of the neutron star is high enough, gravity will overcome neutron degeneracy pressure holding the neutron star up. A black hole will form. However all of the neutron star can't fall into the black hole instantly. A shockwave forms just outside the event horizon that propagates outward. This outgoing shockwave creates the supernova.
What happens to water closest to the moon?
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
What happens within a contracting cloud in which gravity is stronger than pressure?
It continues to contract and collapse. In accordance with Boyle's Law, the compression of any gas also increases the temperature and pressure; at some point, the contraction will stop when pressure and gravity are equally balanced. With a very massive cloud of hydrogen, it's possible that the force of gravity will cause the extreme pressure and temperature sufficient to begin hydrogen fusion. At that point, as they say in Hollywood, "A Star Is Born".
What happens as gravity increases to the pressure on the matter within a star?
As gravity increases so the pressure within the star increases, the matter becomes more dense and hotter, more matter is fused. The star decreases in volume initially. The thermal pressure increases to maintain equilibrium.Depending on the total mass the star may then expand to a giant or 'explode' catastrophically as a nova.
What happens when the gravity of a massive star is ablle to overcome neutron degeneration?
When the gravity of a massive star overcomes neutron degeneracy pressure, it can result in the star collapsing further to form a black hole. This occurs when the mass of the star is above a certain threshold known as the Tolman–Oppenheimer–Volkoff limit, causing the neutron degeneracy pressure to be insufficient to support the star against gravity.
What Materials in the core of a supernova?
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.

What happens as gravity increase the pressure on the matter within a star?
The Rate of Fusion Increases
Does a star 'explode' or 'implode' into a blackhole?
The usual term is "collapse". This happens when the gas and radiation pressure, or degenerate pressure, is no longer enough to counteract gravity.
What force is mainly responsible for the erosion and deposition that happens in landslidesmudslidesand rockfalls?
Gravity is the main force responsible for causing erosion and deposition in landslides, mudslides, and rockfalls. When the force of gravity overcomes the resistance of rocks or soil, these mass movements occur, leading to erosion and deposition of material downslope.
What happens within a contracting cloud in which gravity is stronger than pressure if its temperature remains the same as it contracts?
It breaks into smaller fragments.
When was Gravity Happens created?
Gravity Happens was created on 2011-05-19.

What happens when a liquid is not in a container?
In a gravity free situation, it will eventually stabilize into a sphere if the pressure and temperature conditions are right. In a gravity field the liquid will spread out until it finds the place where it doesn't "run downhill" anymore, if the pressure and temperature conditions are right. However it will stop spreading at a point where the surface tension is greater than the gravity.
What happens to the pressure of the earth as depth below the surface increases?
the pressure decreases the pressure increases
