Which best describes the nuclear reactions that produce energy in the core of the sun?

The type of nuclear reaction taking place in the core of the Sun is known as nuclear fusion and involves hydrogen nuclei combining together to form helium. In the process, a small amount of mass (just under one per cent) is released as energy, and this makes its way to the Sun’s surface before beaming out into space.

What is nuclear reaction in the Sun that produce energy?

The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.

How do the nuclear reactions in the Sun’s core produce energy?

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

What reaction occurs in the core of the Sun?

In the core, pressures and temperatures are high enough to force fusion, that is, nuclear reactions whereby some nuclei merge to make others. It is the type of reaction that powers a hydrogen bomb. The most important reaction within the core of the Sun is the process called the “proton-proton cycle.”

Which type of reaction occurs in the core of a nuclear reactor in a nuclear power plant quizlet?

Uranium-235 undergoes fission to produce two neutrons per fission event.

What describes nuclear fission?

Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. In a nuclear reactor , a neutron is absorbed into a nucleus (typically uranium-235). This causes the nucleus to become uranium-236, which is violently unstable. The entire nucleus splits into two large fragments called ‘daughter nuclei ‘.

What is the overall nuclear fusion reaction in the Sun?

What is the overall nuclear fusion reaction in the Sun? -Nuclear fusion is the source of all energy the Sun releases into space. -The Sun fuses hydrogen at a steady rate, thanks to a natural feedback process that acts as a thermostat for the Sun’s interior (p-p chain).

What is produced from a nuclear fission reaction?

Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.

What type of energy does the Sun produce?

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Where does nuclear fusion occur in the Sun quizlet?

Energy is made through the process of nuclear fusion. This is when two hydrogen nuclei join to make helium. This occurs in the sun’s core where there is very high pressure and temperature.

How is energy transferred from the core of the Sun to its surface?

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. … This transfer of energy can take place by three processes: radiation, conduction, and convection.

What occurs as energy is transferred through the convective zone of the Sun?

What occurs as energy is transferred through the convective zone of the Sun? … Energy is transferred through the large-scale movement of material. Energy is released into the photosphere.

What type of reaction occurs in the core of a nuclear reactor in a nuclear power plant?

Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant. At the center of the reactor is the core, which contains uranium fuel.

Which type of reaction occurs in the core of a nuclear reactor in a nuclear power?

Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.

Which energy transformation occurs in the core of a nuclear reactor nuclear energy mechanical energy?

In nuclear reactors energy in the nucleus is converted to heat energy. Nuclear energy to thermal energy transformation occurs in the core of a nuclear reactor.
