    The fusion reaction is said to the future source of energy. What are the conditions needed to achieve fusion reaction?

    A)  Etremely high pressure and extremely low temperature

    B)  Extremely low pressure and extremely low temperature

    C)  Extremely high pressure and extremely high temperature

    D)  Extremely low pressure and extremely high temperature

    Correct Answer: C

    Solution :

    [c] In nuclear physics, nuclear fusion its a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process mass is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active or 'main sequence' stars. For a fusion reaction to occur, extremely high pressure and extremely high temperature is required.
