China's "artificial sun" marks development in nuclear fusion

The video discusses a fusion reactor reaching 100 million degrees Celsius, over six times the Sun's core temperature. It introduces the Experimental Advanced Superconducting Tokamak (EAST), which uses magnetic fields to contain hot plasma. The nuclear fusion process, where light atom nuclei combine to form a heavier atom, releasing energy, is explained. The ITER project, a multinational effort to harness fusion energy, is mentioned, highlighting that fusion fuels are costly but do not emit harmful pollutants.

What is the temperature achieved by the fusion reactor compared to the Sun's core?

• Same as the temperature

• Over six times the temperature

• Four times the temperature

• Twice the temperature

What shape is the Tokamak reactor?

• Cylindrical

• Spherical

• Rectangular

• Donut-shaped

What prevents the hot plasma in the Tokamak from melting its walls?

• High-pressure air

• Cooling systems

• Magnetic fields

• Thick insulation

What is the result of the nuclear fusion process?

• Formation of lighter atoms

• Creation of magnetic fields

• Release of energy as heat and light

• Absorption of energy

What is a significant advantage of fusion fuels according to the ITER project?

• They do not release harmful emissions

• They release harmful emissions

• They are inexpensive

• They are abundant
