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 is the relationship between gravity and pressure in a nebula?
Gravity is responsible for pulling matter together in a nebula, leading to the formation of stars. As the matter in a nebula collapses under gravity, it increases in density and temperature, which in turn leads to an increase in pressure. The balance between gravity pulling matter inward and pressure pushing outward ultimately determines the fate of the nebula.
What is gravity of the atmosphere?
The force of attraction between the Earth and all other particles of matter in its atmosphere. The acceleration of gravity on Earth is 9.81m/s^2. This means that, no matter what the weight of the object is, it accelerates towards the Earth at 9.81 m each second and the Earth 9.81 m towards it.
What holds the star together?
Stars are held together by their own gravity, which is the result of the balance between the force of gravity pulling matter inward and the pressure created by nuclear fusion reactions in the star's core pushing outward. This equilibrium allows the star to remain stable and maintain its size and shape.
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
What happens as gravity increase the pressure on the matter within a star?
The Rate of Fusion Increases

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.
If the force of gravity increases which measurement will change and how weight decreases mass increases mass decreases weight increases?
If the force of gravity increases, weight will increase because weight is the measure of the force of gravity on an object. However, mass remains constant as it is a measure of the amount of matter in an object and does not change with gravity.
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.
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.
What happens to density when matter increases?
When matter increases, the density typically increases as well. This is because density is a measure of how much mass is in a given volume, so adding more matter without increasing volume will result in a higher density.
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.
