- In considering potential fusion reactions, what is the advantage of the reaction 2H+3H4He+n over the reaction 2H+2H3He+n ?arrow_forwardScientists have continuously been searching for ways to create a system for energy production through fusion reactions but have been unsuccessful. Which of the following explains why it is still not a practical source of power? O Fusion can create a huge amount of energy with very little fuel. O Fusion radioactive byproducts have a shorter half-life than fission byproducts. O Fusion requires a large amount of energy to force atoms to initially fuse together. O Fusion reactions have virtually little to no risk of nuclear accidents.arrow_forwardConsider equal numbers of deuterium and tritium nuclei fusing to form helium-4 nuclei, as given in the image. part a) What is the yield in joules of kinetic energy liberated per kilogram of fuel? part b) How does this compare with a typical yield of 10^6 J/kg for chemical fuels?arrow_forward
- Explain why the deuterium tritium mixture must be extremely hot in order for the fusion reaction to occur.arrow_forwardWhich process would release energy from gold, fission or fusion? Which would release energy from carbon? From iron?arrow_forwardChoose the BEST answer to the following. The equation that most underlies energy release in nuclear events is (a) E = hf. (b) E = = 1/2 mv2 (c) E = Fd (c) E = mc2arrow_forward
- Ordinary hydrogen is sometimes called a perfect fuel, both because of its almost unlimited supply on Earth and because, when it burns, harmless water is the product of the combustion. So why don’t we abandon fission and fusion energies, not to mention fossil-fuel energy, and just use hydrogen?arrow_forwardYou are having a family holiday dinner with your extended family: grandparents, aunts, uncles, cousins, etc. The conversation turns to your studies in physics, and you tell everyone about your studies about fusion reactions in the Sun. One of your nephews says, “Oh, yeah? I think the Sun is just a big ball of gasoline burning away. How can you prove that that isn’t true?” (a) Based on the fact that gasoline delivers about 1.3 x 10^8 J of energy for each gallon burned, perform a calculation that will show your nephew how long the Sun would last if it were made of gasoline. (b) Perform a calculation to show your nephew that nuclear fusion of all the hydrogen in the Sun could last a lot longer.arrow_forwardWhy is there, unlike fission fuel, no limit to the amount of fusion fuel that can be safely stored in one locality?arrow_forward
- Explain why the fusion reaction of atomic nuclei-the formation of lighter nuclei of heavier ones-is a colossal source of energy.arrow_forwardFor a fusion reaction, at which temperature T do you expect the optimal reaction rate to approximately occur?

Fission is about one nucleus breaking apart while fusion is about two nuclei joining together. Fusion is about one nucleus breaking apart while fission is about two nuclei joining together. There is no difference between fission and fusion. Fusion is used in nuclear reactors while fission is not.arrow_forward
