La fusión nuclear: fusión fría y caliente

The video discusses nuclear fission and fusion, highlighting the energy released by these processes. It explains the challenges of achieving nuclear fusion, particularly the high temperatures required. In 1989, Dr. Flashman's team claimed to have achieved cold fusion, but their results were later debunked by the scientific community. The video concludes that hot fusion remains the only scientifically accepted method for nuclear fusion.

What is the primary difference between nuclear fusion and fission?

• Fusion involves splitting a heavy nucleus, while fission combines light nuclei.

• Fusion requires high temperatures, while fission does not.

• Fission releases more energy than fusion.

• Fusion is a process that occurs naturally on Earth.

What was the scientific community's expectation in the 1980s regarding nuclear fusion?

• That fusion was impossible to achieve.

• That fusion could be achieved at low temperatures.

• That fusion would replace all other energy sources immediately.

• That fusion could be achieved without any energy input.

What did Dr. Flashman's team claim to have achieved in 1989?

• A new method of nuclear fission.

• A method to reduce the temperature required for hot fusion.

• Cold fusion in a test tube.

• A way to produce energy without nuclear reactions.

What was the main flaw in the cold fusion experiments?

• The neutrons detected were from the natural environment, not from fusion.

• The experiments required more energy than they produced.

• The experiments did not produce any energy.

• The experiments were too expensive to replicate.

What is the current scientifically accepted method to achieve nuclear fusion?

• Magnetic fusion

• Chemical fusion

• Hot fusion

• Cold fusion
