When the pressure and temperature of a nebula increases what is formed?
When the pressure and temperature of a nebula increase, it can lead to the formation of protostars. As gravity causes the nebula to contract and heat up, eventually nuclear fusion can begin at the core of the protostar, leading to the formation of a new star.
What works with pressure to keep a nebula from collapsing?
The pressure caused by the thermal energy of the gas within the nebula pushes outward in all directions, preventing the nebula from collapsing under its own gravity. This pressure acts to counterbalance the force of gravity, maintaining the nebula's size and structure.
How did pressure and gravity become unbalanced in the solar nebula?
Pressure and gravity became unbalanced in the solar nebula due to the gravitational collapse of gas and dust. As the cloud of gas and dust contracted under the force of gravity, the pressure increased at the center, causing the core to heat up and eventually ignite nuclear fusion, leading to the formation of the Sun.
How do gravity and pressure keep a nebula from collapsing?
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.
What two forces stabilize a nebula?
Gravitational force pulls gas and dust particles together to form a nebula, while the outward pressure from gas particles pushing against each other (thermal pressure) prevents the nebula from collapsing under gravity. These two forces work together to stabilize a nebula.
