Question

Give reasons justifying the contention made in the that energy from the fusion reaction 2H+2H→4He+γ is relatively difficult to capture and utilize.

a) Gamma rays are difficult to absorb and convert.

b) Helium is a poor energy carrier.

c) The reaction produces low-energy gamma rays.

d) Gamma rays escape easily from the reaction site.

Answer 1

Capturing energy from the fusion reaction 2H + 2H → 4He + γ is challenging due to the difficulty in absorbing and converting gamma rays, helium's ineffectiveness as an energy carrier, and the tendency of gamma rays to escape the reaction site.

Step-by-step explanation:

The contention that energy from the fusion reaction 2H + 2H → 4He + γ (gamma ray) is difficult to capture and utilize can be explained by a few factors. Firstly, gamma rays are highly energetic and thus difficult to absorb and convert into usable forms of energy. Secondly, while the reaction does produce a large amount of energy, helium does not act as a helpful carrier of this energy. Lastly, the high penetration power of gamma rays means they tend to escape easily from the reaction site, making energy capture less efficient.
