How Much Energy Is Released in a Nuclear Fission Explosion of 5kg of Uranium?

In summary, nuclear fission is a process in which an atom's nucleus splits into two smaller nuclei, releasing a large amount of energy. It is primarily used to generate electricity in nuclear power plants, but also has applications in weapons and medical treatments. The main risks associated with nuclear fission are accidents and the production of radioactive waste. It differs from nuclear fusion, which involves combining atoms, and is still in the experimental stage for energy production. While nuclear fission can be a source of sustainable energy, it is not renewable as it requires limited resources and proper safety measures and waste management must be in place.

Hi, I am studying in 10th Standard and preparing for final exams,
anyone please help for this following question.

When Uranium undergoes Nuclear Fission, 0.1 %(percentage) of total mass is converted into energy. Calculate tota amount of energy in Joules during an explosion of atom bomb which contains 5kg of Uranium.

Please help me with the above question with steps, I will be very thankful to you all.

Thanks,
Rahhavender.

It looks like you need to convert 5 grams of matter to energy, using E=mc2. You need a conversion table, which might give you grams to joules conversion directly.

Hi Rahhavender,

To calculate the total amount of energy released during a nuclear fission reaction, we can use the famous equation E=mc^2, where E is energy, m is mass and c is the speed of light (approximately 3x10^8 m/s).

First, we need to convert the mass of Uranium from kilograms to grams, since the percentage given is in grams. This can be done by multiplying 5kg by 1000 to get 5000g.

Next, we need to calculate the mass that is converted into energy. Since it is only 0.1% of the total mass, we can multiply 5000g by 0.001 to get 5g.

Now, we can plug these values into the equation E=mc^2. This gives us E=(5g)(3x10^8 m/s)^2. Simplifying this, we get E=5x9x10^16 J, which is equal to 4.5x10^17 J.

Therefore, the total amount of energy released during the explosion of an atom bomb containing 5kg of Uranium is 4.5x10^17 Joules.

I hope this helps you with your exam preparation. Best of luck!


 

Related to How Much Energy Is Released in a Nuclear Fission Explosion of 5kg of Uranium?

1. What is nuclear fission?

Nuclear fission is a process in which an atom's nucleus splits into two smaller nuclei, releasing a large amount of energy in the form of heat and radiation.

2. How is nuclear fission used?

Nuclear fission is primarily used to generate electricity in nuclear power plants. It is also used in nuclear weapons and in some medical treatments.

3. What are the risks associated with nuclear fission?

The main risks associated with nuclear fission are the potential for accidents and the production of radioactive waste. Accidents can release harmful radiation into the environment, and the disposal of nuclear waste is a complex and ongoing issue.

4. What is the difference between nuclear fission and nuclear fusion?

Nuclear fission involves splitting atoms, while nuclear fusion involves combining atoms. Fission is used in nuclear power plants, while fusion is still in the experimental stage for energy production.

5. Can nuclear fission be harnessed for sustainable energy?

Nuclear fission can be a source of sustainable energy if proper safety measures are in place and nuclear waste is managed responsibly. However, it is not a renewable energy source as it requires uranium, a limited resource, as fuel.
