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 as gravity increases the pressure on the matter within a star?
The Rate of Fusion Increases
What role did gravity play in forming the sun?
The sun (Sol), like any star, gained so much mass (of mainly hydrogen, with some helium and lithium) that its core began a fusion reaction. Without gravity, it would not have had enough mass, and by extent pressure, to sustain fusion, and therefore would not be a star.
Is gravity the force of the earth on objects near it?
Gravity is not unique to the Earth. All matter has gravity and all matter attracts all other matter. Since the Earth has mass it also has a gracvitational field associated with it.
What determines your weight on a planet?
Both it's mass and the force of gravity acting on it
What forces cause the accumulation of matter that form stars?
Well what the problem is really adressing is what force causes the accumulation of matter or the nebulae to form stars. Simply gravity. The nebulae collapes due to a concentrated point of gravity. All that matter collapes into a star. So the answer is gravity.

Why does the exosphere have the least amount of pressure?
Air pressure decreases as altitude increases. Matter is held by gravity. The same reason that pressure is greatest in the core, the least pressure is farthest from the core. Matter "thins - out". The heaviest elements are always in the center and the lightest are furthest from the center.

What happens to the volume of matter when it expands?
It increases.
What happens to weight as mass increases?
Nothing, "mass" is a property of matter and is constant. Weight is the force of attraction of one mass to another (the affect of gravity on a mass). Thus if weight increases it means that the mass is in a stronger gravity field.
Why gravity decreases as you go down the earth surface?
the gravity does not decrease it increases because their is more matter the deeper you go down into the earth.
How can you explain gravity?
Gravity is the attraction between all matter. The force of gravity increases as matter gets closer together, and it increases as more matter is gathered. For example, that computer you are sitting in front of is attracting you, and you are attracting it. However, due to the immense gravity exerted by the earth, it is almost unnoticeable. Gravity was explained by Sir Isaac Newton, the man who is believed to be the developer of the theory of gravity. It is basically the driving force of the universe. Gravity is the driving force of the universe. It is the force that created planets, and it's the force that gives black holes their immense power. Gravity holds the whole world together.
What happens when pressure decreases?
Air pressure decreases as you move higher in the atmosphere. Air, just like any form of matter has mass, and when affected by earth's gravity, weight. The weight of air is pushing down on you with a force of 1 atmosphere at sea level. As you increase elevation the air pressure is reduced because there is less air to push down on you. Just like air, water pressure increases as you increase your depth in it, or any fluid. When air pressure decreases, temperature drops.
Why is the earth denser as you go deeper under ground?
Because the pressure increases with depth. The same as if you go underwater, the weight of water above you increases as you go deeper, exerting a greater pressure on your body. This greater pressure decreases the unit volume of the matter, so the density increases.
How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
Is gravity matter why or why not?
Gravity is NOT matter, it is a force that effects matter.
