Q
Q: In nuclear fission, the mass of the products is less than the mass of the reactants. What is this mass difference called? (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.
Steps: 5
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.
