Understanding Fission Reactions: Calculating Energy & Mass in Joules and MeV

In summary, a fission reaction is a type of nuclear reaction that splits the nucleus of an atom into smaller nuclei and releases a large amount of energy. This energy can be calculated using the equation E=mc^2, where E is energy, m is mass, and c is the speed of light. The unit of energy commonly used in fission reactions is the joule (J), but it can also be expressed in electron volts (eV) or mega electron volts (MeV). The mass involved in a fission reaction can be calculated using the equation m=E/c^2, which allows for the conversion of mass into energy and vice versa. Additionally, energy and mass can be converted between units using the equation E=mc

How do we determine the values of any given fission reaction?

How do we answer questions like: A decrease in mass of 3.48x10(to the power of -28) kg occurs. Express the energy equivalent of this in terms of joules and MeV.

I keep reading and reading but can't understand. I search online but still can't get the general and advanced concepts of Physics. It asks all these worded questions which I don't get, is there a easier/better way to practice Energy from The Nucleus?? Thank you.

1. What is a fission reaction?

A fission reaction is a type of nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, releasing a large amount of energy in the process.

2. How is energy calculated in fission reactions?

The energy released in a fission reaction can be calculated using the famous equation E=mc2, where E is energy, m is mass, and c is the speed of light. The change in mass before and after the reaction can be used to calculate the amount of energy released.

3. What is the unit of energy used in fission reactions?

The unit of energy commonly used in fission reactions is the joule (J). However, the energy released in nuclear reactions is often expressed in electron volts (eV) or mega electron volts (MeV) for convenience.

4. How is mass calculated in fission reactions?

The mass of the particles involved in a fission reaction can be calculated using the equation m=E/c2. This equation allows us to determine the amount of mass that is converted into energy during the reaction.

5. Can the energy and mass in fission reactions be converted between units?

Yes, the energy and mass in fission reactions can be converted between units using the equation E=mc2. For example, to convert energy from joules to MeV, you would divide the energy in joules by 1.602 x 10-13 (the conversion factor from joules to MeV).
