The Rate of Fusion Increases
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.
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.
You cannot increase gravity, but you can increase the force of gravity on a piece of matter with mass by1. Making the piece of matter larger2. Making it more dense3. Moving it closer to the center of a separate piece of matter.
No, gas gravity and specific gravity are not the same. Gas gravity refers to the ratio of the density of a gas to the density of air, while specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water.
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.
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
The three types of pressure that can push against the inward force of gravity are thermal pressure (due to high temperatures), radiation pressure (from electromagnetic radiation), and degeneracy pressure (resulting from quantum effects in dense matter).
As matter from a nebula condenses, it begins to form into clumps due to gravity. These clumps eventually evolve into protostars, as heat and pressure increase at their cores, initiating the process of nuclear fusion. This marks the beginning of a star's life cycle.
Gravity is NOT matter, it is a force that effects matter.
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.
