1. The minimum mass of a fissile material necessary to sustain the chain reaction is called  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled.
2. The atom bomb is based on the principle of  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled chain reaction.
3.  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled is the unit used in nuclear physics to measure the energy of small particles.
4. The process in which two lighter nuclei combine to form a heavier nucleus is termed as  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled.
5. The mass of the daughter nucleus formed during a nuclear reaction (fission and fusion) is lesser than the sum of the masses of the two parent nuclei. This difference in mass is called  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled.
6. Fusion reaction that takes place in the cores of the Sun and other stars results in an enormous amount of energy, which is called as  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled.
7. The radio isotope of  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled helps to increase the productivity of crops.
8. Radio  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled is used for the effective functioning of heart.
9. Radio  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled is used to diagnose anaemia and also to provide treatment for the same.
10. A  critical massElectron Voltironmass defectmoderatornuclear fusionphosphoroussodiumstellar energyuncontrolled is used to slow down the high energy neutrons to provide slow neutrons.
