Why does heat build up more rapidly in a massive protostar than in a less massive one?
A protostar starts forming when the gas particles start getting attracted towards one another with gravity. When they cannot be bound any closer the gravitational energy is transformed into thermal energy. With more massive protostars there is also more gravity available to become thermal energy.

What two forces are within a protostar?
Gravitational force - which pulls matter towards the center of the protostar and is responsible for its contraction. Thermal pressure - which is generated by the heat and pressure within the protostar's core and pushes outward to counteract the gravitational force.
What is the temperature of a protostar?
the color of the protostar is red
How hot is the core of a protostar?
The core will reach between 250,000,000 to 500,000,000'C at its stable temperature. Beforehand it will rapidly gain heat from hundreds of thousands to its stable temperature, where it can begin the process of nuclear fusion. Hope that helps!
What is the differences of a protostar and a white dwarf?
A protostar is a star that is still forming and has not yet started a sustained fusion reaction. All the heat is the result of gasses being compressed. A white dwarf is the remnant of a dead star that has exhausted its fuel and is much smaller and denser than a protostar.
What must happen before a protostar will glow?
Before a protostar can start glowing, it must finish collecting enough gas and dust to trigger nuclear fusion in its core. This process requires the protostar to reach a temperature and pressure high enough for hydrogen atoms to fuse together, releasing energy as light and heat.

What is generated by the pressure caused by gravity inside a protostar?
Intense heat. If you are looking for the answer to a crossword puzzle it may just be "heat".

How does heat build up in a protostar?
What a nice question. Gravity is a major force, and in so acting, it brings the various atoms and molecules closer together. This necessarily includes their state of energy - if an atom had a certain kinetic energy, then even when compressed with similar, one would now have a higher density of energy within the new smaller volume.

A protostar is a star that is still forming and has not yet started a sustained fusion reaction. All the heat is the result of gasses being compressed. A white dwarf is the remnant of a dead star that has exhausted its fuel and is much smaller and denser than a protostar.
What happens to the surface temperature and luminosity when gravity first assembles a protostar from a collapsing cloud?
As gravity collapses the cloud to form a protostar, the temperature and luminosity both increase. The increase in temperature is due to the compression of material, causing the protostar to heat up as energy is released. The increase in luminosity is a result of the protostar radiating this energy.
What must happen before a protostar will glow?
Before a protostar can start glowing, it must finish collecting enough gas and dust to trigger nuclear fusion in its core. This process requires the protostar to reach a temperature and pressure high enough for hydrogen atoms to fuse together, releasing energy as light and heat.
What keeps a protostar from collapsing?
A protostar is supported against gravitational collapse by the outward pressure generated from the heat produced by gravitational contraction. This pressure, known as radiation pressure, acts to counterbalance the force of gravity pulling the protostar inward. As the protostar continues to contract, it eventually reaches a point where nuclear fusion ignites in its core, providing an additional outward pressure that stabilizes the star against collapse.
When does a protostar become a star?
The basic idea is that the protostar contracts, under the influence of gravity, until it gets dense and hot enough to undergo nuclear fusion. You can find more details at the Wikipedia article "Protostar".
What is the beginning stage in the formation of a star called?
The beginning stage in the formation of a star is called a protostar. This is when a dense core within a molecular cloud begins to accumulate gas and dust, causing it to heat up and eventually become a star.
What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
