What forces must be balanced in order for a star to continue to shine?

There are basically two forces that are responsible for the balancing of stars. These forces are respectively the inward gravity of the star and outward push of pressure created by heat energy due to fusion reactions. These two forces always keep a star in equilibrium and hinder their collapse.

What are the two forces that must be in balance so a star can shine?

A star is okay as long as the star has this equilibrium between gravity pulling the star inwards and pressure pushing the star outwards. During most a star’s lifetime, the interior heat and radiation is provided by nuclear reactions in the star’s core.

What are the two forces that must be balanced in order for a star to be stable?

(2) Which two forces are in balance for a main sequence star? While self-gravity pulls the star inward and tries to make it collapse, thermal pressure (heat created by fusion) pushes outward. These two forces cancel each other out in a main sequence star, thus making it stable.

What forces balance to determine the size of a star?

The size of a star is a natural consequence of the balance between the inward pull of gravity and the outward pressure of radiation produced inside the star. When these two forces are balanced, the outer layers of the star are stable and said to be in hydrostatic equilibrium.

What are the forces involved in star formation?

Remember that the essence of the life story of any star is the ongoing competition between two forces: gravity and pressure. The force of gravity, pulling inward, tries to make a star collapse. Internal pressure produced by the motions of the gas atoms, pushing outward, tries to force the star to expand.

What is the force that keeps a main sequence star from blowing apart?

What is the force that keeps a main sequence star from blowing up? Stars on the main sequence are those that are fusing hydrogen into helium in their cores. The radiation and heat from this reaction keep the force of gravity from collapsing the star during this phase of the star’s life.

How do stars form step by step?

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.

What are the stages of star?

Seven Main Stages of a Star

• Giant Gas Cloud. A star originates from a large cloud of gas. …
• Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced. …
• T-Tauri Phase. …
• Main Sequence. …
• Red Giant. …
• The Fusion of Heavier Elements. …
• Supernovae and Planetary Nebulae.

What causes a star to shine brightly?

Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.

What are the 3 end stages of stars?

Three and stages of stars are white dwarf, neutron star and a black hole.

What is the order of a stars life cycle?

as our sun (just on a larger scale) upto the Main Sequence stage, Then the massive stars expand into a Red Supergiant, Explode into a Supernova, Then turn into a Black Hole or a Neutron Star.

What are the 4 stages of a star?

The formation and life cycle of stars

• A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula. …
• Protostar. As the mass falls together it gets hot. …
• Main sequence star. …
• Red giant star. …
• White dwarf. …
• Supernova. …
• Neutron star or black hole.

What is the next stage in a star’s life after the main sequence phase?

Explanation: After the main sequence stage in which a Star burn it’s Hydrogen into Helium, the Star rearranges it self expanding it’s outer layers and shrinking its core becoming a Red-Giant.
