Which best compares the difference between how the sun generates energy and how human built nuclear power plants generate energy?

Which best compares the difference between how the sun generates energy and how human-built nuclear power plants generate energy quizlet?

Which of the following correctly compares the Sun’s energy generation process to the energy generation process in human-built nuclear power plants? The Sun generates energy by fusing small nuclei into larger ones, while our power plants generate energy by the fission (splitting) of large nuclei.

How do human-built nuclear power plants on Earth generate energy?

How do human-built nuclear power plants on Earth generate energy? … Fusion reactions decrease the overall number of particles in the core, causing the core to shrink, converting gravitational potential energy into thermal energy, and increasing the rate of fusion.

Do nuclear power plants on Earth create energy in the same way as the sun?

The Sun generates energy primarily by nuclear fission. Nuclear power plants on Earth create energy in the same way as the Sun. … Energy from the core of the Sun first travels slowly through the convection zone and then much faster through the radiation zone.

Which of the following is the best answer to the question why does the sunshine?

Which of the following is the best answer to the question, “Why does the Sun shine?” As the Sun was forming, gravitational contraction increased the Sun’s temperature until the core become hot enough for nuclear fusion, which ever since has generated the heat that makes the Sun shine.

Which of the following correctly compares the sun’s energy generation process?

Which of the following correctly compares the Sun’s energy generation process to the energy generation process in human-built nuclear power plants? The Sun generates energy by fusing small nuclei into larger ones, while our power plants generate energy by the fission (splitting) of large nuclei.

How does the sun generate energy quizlet?

The Sun generates energy through the process of Nuclear Fusion in its core. Exactly what happens in the process of Nuclear Fusion? Nuclear Fusion is the process by which two or more low-mass nuclei (Hydrogen) fuse to form another heavier nucleus (Helium).

How does the Sun generate energy?

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

How does the Sun generate energy today?

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. … The radiant energy travels to the Earth at a speed of 186,000 miles per second, the speed of light.

How does the Sun’s mass compare to Earth’s mass?

The Sun’s mass is about 300 times the mass of the Earth. Both have approximately the same mass. The Sun’s mass is about 300,000 times the mass of the Earth.

How is nuclear power different from the Sun’s energy?

Nuclear energy does derive from a star, but not the sun. Stars use fusion reactions to turn matter into energy. … Nuclear power is not solar in the same way that wind, hydroelectric, photovoltaic, or even fossil fuels, which are derived ultimately from plant matter, are.

How is the Sun different from a nuclear power plant?

The sun obtains its energy when atoms join together to form a heavy energy-filled atom. In contrast, nuclear power plants work through fission, a process of splitting atoms, where uranium atoms split to produce heat separated by a coolant that turns water into steam.

How is nuclear energy related to the Sun?

The proton-proton fusion process that is the source of energy from the Sun. The energy from the Sun – both heat and light energy – originates from a nuclear fusion process that is occurring inside the core of the Sun. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.

THIS IS UNIQUE:  You asked: What is the best definition of alternative energy?

Which of the following best explains why the Sun’s luminosity?

Which of the following best explains why the sun’s luminosity gradually rises over billions of years? Fusion gradually decreases the number of independent particles in the core, allowing gravity to compress and heat the core, which in turn increases the fusion rate and the Sun’s luminosity.

What makes the Sun to shine?

The Sun shines by turning hydrogen into helium in its core. This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.

How large is the Sun’s core compared to the rest of the Sun?

The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius. It is the hottest part of the Sun and of the Solar System. It has a density of 150 g/cm3 at the center, and a temperature of 15 million kelvins (15 million degrees Celsius, 27 million degrees Fahrenheit).
