Question: In nuclear fission, the mass of the products is less than the mass of the reactants. What is this mass difference called? (2019)

Options:

Correct Answer: Mass defect

Exam Year: 2019

Solution:

The mass difference in nuclear fission is referred to as the mass defect, which is converted into energy according to Einstein\'s equation E=mc².

In nuclear fission, the mass of the products is less than the mass of the reactants. What is this mass difference called? (2019)

Step 1: Understand that nuclear fission is a process where a heavy nucleus splits into smaller nuclei.
Step 2: Recognize that during this splitting, some mass is lost.
Step 3: Identify that the mass of the products (smaller nuclei) is less than the mass of the original reactants (heavy nucleus).
Step 4: Learn that this lost mass is called the 'mass defect.'
Step 5: Know that the mass defect is converted into energy, which can be calculated using Einstein's equation E=mc².

Mass Defect – The difference in mass between the reactants and products in a nuclear reaction, which is converted into energy.
Einstein's Equation – The relationship between mass and energy, expressed as E=mc², indicating that mass can be converted into energy.
Nuclear Fission – A process in which the nucleus of an atom splits into smaller parts, releasing energy.
