nuclear fusion

• What is nuclear fusion?

  When two lighter nuclei join to form one larger nucleus
• What process is responsible for fueling stars?

  Nuclear fusion
• How were elements heavier than hydrogen made?

  Through nuclear fusion
• Why does fusion produce large amounts of energy?

  Some mass is converted into energy
• According to the text, where does the energy released come from during nuclear fusion?

  A tiny amount of mass being converted into energy
• What is a major advantage of nuclear fusion as an energy source?

  It doesn't produce radioactive waste
• According to the text, what is a benefit of hydrogen as nuclear fuel?

  It can be easily made
• What is the primary obstacle to achieving practical nuclear fusion on Earth?

  Extremely high temperatures and pressures needed
• What temperature, according to the text, is required for nuclear fusion?

  10 million degrees Celsius
• What kind of research is being conducted to overcome the challenges of nuclear fusion?

  Experimental research
• According to the text, where does nuclear fusion naturally occur?

  Inside stars
• What happens to the mass of the resultant nuclei, relative to the mass of the original nuclei, during fusion?

  The resultant nuclei are slightly lighter
