MCQ
Nuclear fusion reactions cannot be harnessed for productive applications because:
  • A
    These reactions require very high temperature and are controllable.
  • B
    These reactions require very high temperature and are uncontrollable.
  • C
    These reactions require very low temperature and are uncontrollable.
  • D
    These reactions require very low temperature and are controllable.

Answer

  1. These reactions require very high temperature and are uncontrollable.

Explanation:

Fusion reaction is the combining of atom to form heavier nuclei. Fusion reaction requires high temperature. God fusion to occur on earth a, we need a temperature of at least 100 million degree Celsius. It is also an uncontrollable reaction.
