where, most importantly P=pressure and T=Temperature. The outward pressure nearly balances the inward gravitational pull, ... The inward pull of gravity is balanced by the gas pressure which is determined by the Ideal Gas Law: PV=NRT. ... The contraction of the core causes the temperature and density to increase such that,

The disturbance causes clumps to form inside the cloud. ... The young star is now stable in that the outward pressure from hydrogen fusion balances the inward pull of gravity. The star enters the main sequence; where it lies on the main sequence depends upon its mass.

The balloon at room temperature remains unchanged, but chilling the balloon in the freezer causes it to shrink and sink into the jar. ... As long as the outward pressure balances the inward pull of gravity, the star remains stable in size. When the nuclear reactions stop, the balance is upset, and gravity pulls the star...

During most of a star's lifetime, nuclear fusion in the core generates electromagnetic radiation, including photons, the particles of light. This radiation exerts an outward pressure that exactly balances the inward pull of gravity caused by the star's mass.

This energy from fusion pours out from the core, setting up an outward pressure in the gas around it that balances the inward pull of gravity. ... Without the outward pressure generated from these reactions to counteract the force of gravity, the outer layers of the star begin to collapse inward toward the core.
