Korea’s tokamak artificial sun sets new plasma record

The video explains the tokamak, a device that recently set a world record by maintaining plasma at over 100 million degrees Celsius for 20 seconds, marking progress in nuclear fusion for clean energy. It describes the fusion process where lighter atomic nuclei combine to release energy. The video details how hydrogen isotopes are used in a tokamak to create plasma, which is confined by powerful magnetic fields to prevent it from touching the machine. The goal is to keep the plasma stable long enough for fusion reactions to occur.

What is the significance of the tokamak achieving plasma temperatures over 100 million degrees Celsius for 20 seconds?

Explain the process of nuclear fusion as described in the text.

What role do hydrogen isotopes play in the fusion process within a tokamak?

Describe how the magnetic fields in a tokamak function to maintain plasma stability.

What are the potential consequences if the plasma were to escape the confinement of the tokamak?
