Gravity pulls the particles in a nebula towards the center, trying to collapse it. However, pressure from gas and radiation within the nebula counteracts gravity, creating a balance that prevents collapse. This balance is crucial for the formation of stars from a nebula.
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
In a nebula, gravitational forces act to pull the gas and dust inward, while thermal pressure, generated by the heat from the particles and radiation from nearby stars, acts outward to counterbalance this gravitational pull. The balance between these two forces prevents the nebula from collapsing under its own gravity, allowing it to maintain its structure until conditions change, potentially leading to star formation.
The structure of the lungs, which are surrounded by a lining called the pleura, helps to keep them inflated. The pleural pressure is lower than the pressure inside the alveoli, creating a partial vacuum that prevents the lungs from collapsing. Additionally, the presence of surfactant in the alveoli reduces surface tension, helping to maintain lung expansion.
In a nebula, gravity pulls gas and dust particles together, creating an inward force that can lead to the formation of stars. However, as these particles clump together, they also generate pressure from the heat produced by collisions and gravitational compression. This pressure acts outward, counterbalancing the inward pull of gravity. The balance between gravitational attraction and the outward pressure determines the stability of the nebula and influences whether it will collapse to form stars or remain diffuse.

To keep them from collapsing due to negative pressure on an exhale.
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
The balance of forces that keep a star from collapsing is called hydrostatic equilibrium. This equilibrium is maintained between the inward force of gravity and the outward force generated by gas pressure within the star.

The air pressure inside the water bottle helps to maintain its shape and prevent it from collapsing as water is consumed or as external pressure is applied to the bottle. Additionally, the air pressure helps to keep the water inside the bottle from leaking out.
