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.

What is the difference between a nebula and a protostar?
A nebula is a vast cloud of gas and dust in space, while a protostar is a dense region within a nebula where gravity causes material to come together and heat up, eventually leading to the formation of a star. In essence, a protostar is a stage in the formation process of a star within a nebula.
What is a contracting cloud of gas and dust with enough mass to form a star?
it's a protostar
A nebula begins the process of becoming a protostar when the nebula?
begins to collapse under its own gravity due to a disturbance, such as a shockwave from a nearby supernova. As the nebula collapses, it heats up and the particles within it start to come together, initiating the formation of a protostar.
Carbon dioxide is a greenhouse gas that causes what?
Greenhouse gases build up in the atmosphere and absorb heat so it can not escape making earth warmer. It is called Global Warming.
Would a glass or copper rod heat up first and why?
A copper rod would heat up first because it is a better conductor of heat compared to glass. Copper transfers heat more efficiently due to its high thermal conductivity, allowing it to absorb and distribute heat faster than glass.
What is the temperature of a protostar?
the color of the protostar is red
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.
Explain why a protostar heats up internally as its gravitationally contracts?
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.
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 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 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.
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".
Is a new star called a protostar?
Yes, a new star that is in the process of formation is called a protostar. It is the early stage in the life cycle of a star when gravitational forces are causing gas and dust to condense and heat up, eventually leading to nuclear fusion and the birth of a stable star.
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.
Why does a protostar heat up internally as it contracts?
A protostar heats up internally as it contracts due to the gravitational potential energy being converted into thermal energy. The collapse of the gas cloud causes an increase in density and pressure, leading to a rise in temperature at the core. This process eventually triggers nuclear fusion and marks the start of a star's life cycle.
What do stars start out as in the process of their formation and evolution?
Stars start out as clouds of gas and dust in space. Through the process of gravitational collapse, these clouds condense and heat up, eventually forming a protostar. As the protostar continues to accumulate mass, nuclear fusion reactions begin in its core, leading to the birth of a star.
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.
