Why is the end result of nuclear fusion less dense than its original parts?

The end result of nuclear fusion is dense than its original parts because in fusion they lose some of their energy.

Nuclear fusion involves combining light atomic nuclei to form a heavier nucleus, releasing energy in the process. This process releases energy in the form of electromagnetic radiation and kinetic energy of the particles involved, which can cause the resulting nucleus to have less mass than the original nuclei that fused. The mass lost is converted into energy according to E=mc^2, as described by Einstein's theory of relativity.

If a protostar doesn't undergo a nuclear fusion what will it turn into?
If a protostar does not undergo nuclear fusion, it will not become a star. Instead, it will either become a brown dwarf, which is a failed star that lacks the mass to sustain nuclear fusion, or it will simply cool down into a cold, dense object known as a sub-stellar object.
Stars can form most easily in clouds that are?
Cold, dense, and massive. These conditions allow gravity to overcome internal pressure and initiate the process of nuclear fusion, leading to the formation of a star.
Are stars really hollow?
Stars are not hollow. Stars are massive objects made primarily of a hot, dense core of gas undergoing nuclear fusion. This fusion process generates immense amounts of energy and pressure, causing the star to expand and emit light.
Does hydrogen fusion occur in the corona?
Hydrogen fusion does not occur in the corona of the sun. Fusion reactions occur in the sun's core where conditions are hot and dense enough for hydrogen nuclei to combine to form helium, releasing energy in the process. The corona is cooler and less dense than the core, so fusion cannot take place there.
What is nuclear energy?
Nuclear energy is energy that is released through nuclear reactions, either by splitting atoms (nuclear fission) or combining them (nuclear fusion). This energy can be harnessed to generate electricity in nuclear power plants.
Why does the sun give off so many energy?
It gets the energy from nuclear fusion. It is able to carry out this nuclear fusion because of its mass, which pulls the Sun together, and keeps its core hot and dense.
What is the process that A star turns matter into energy?
A nuclear reaction - either fusion or fission - is required to turn matter into energy.
Why is nuclear fusion possible in the sun?
Nuclear fusion occurs in stars due to the shear density of a star. They are so dense that the pressure in the core ionizes hydrogen, stripping them into bare atoms. The inward gravitational pull of the dense core causes the atoms to be smashed together, fusing into helium. The energy from the fusion provides enough outward pressure to counteract the core's own gravity.
A protostar forms once the nebular cloud condenses and the core begins?
to grow dense and hot due to gravitational contraction. As the core heats up, it triggers the start of nuclear fusion, becoming a main sequence star.
If a protostar doesn't undergo a nuclear fusion what will it turn into?
If a protostar does not undergo nuclear fusion, it will not become a star. Instead, it will either become a brown dwarf, which is a failed star that lacks the mass to sustain nuclear fusion, or it will simply cool down into a cold, dense object known as a sub-stellar object.
Why no fission on sun?
The core of the Sun is not dense or hot enough to sustain nuclear fission reactions like those in nuclear power plants. Instead, the Sun undergoes nuclear fusion, where lighter elements are combined to form heavier ones, releasing vast amounts of energy in the process. This fusion process sustains the Sun's energy output and keeps it shining.
Why doesnt Jupiter make nuclear fusion?
Jupiter is not nearly massive enough or dense enough to hit "critical mass"; essentially, there's not enough pressure at the core of the planet to start the initial nuclear reaction and its not dense enough to maintain the reaction.
Stars can form most easily in clouds that are?
Cold, dense, and massive. These conditions allow gravity to overcome internal pressure and initiate the process of nuclear fusion, leading to the formation of a star.
Where would you find the least dense elements in a star?
Denser elements in a star tend to condense near the star's core, while less dense elements generally move outward towards the surface to take place in nuclear fusion.
Does a main sequence star maintain a stable size?
After a star has formed, it creates energy at the hot, dense core region through the nuclear fusion of hydrogen atoms into helium.
What the most dense part of the sun?
The core is the most dense part of the sun, where temperatures and pressures are extremely high, enabling nuclear fusion to occur. This fusion process releases energy in the form of light and heat that eventually reaches the surface of the sun.
What events led to birth of sun?
gravity pulled most of the gas into the center of the disk,where the gas eventually became hot and dense enough for nuclear fusion to begin. the sun was born
