The process in which a heavy nucleus splits into two lighter nuclei with the release of enormous energy is called: MCQ with Answer and Explanation

Explanation:
PV = constant at constant T and n. This is Boyle's law. If either P or V changes, the other changes inversely.

Explanation:
Sulfur forms cross-links between polyisoprene chains, converting sticky raw rubber into strong, elastic material. Process discovered by Goodyear.

Explanation:
Combustion of methane (CH₄ + 2O₂ → CO₂ + 2H₂O + heat) is an exothermic reaction, releasing heat to surroundings. Melting, evaporation, and sublimation are endothermic phase changes requiring heat absorption to overcome intermolecular forces. Exothermic reactions: burning, respiration, neutralization (usually), condensation, freezing. Endothermic: photosynthesis, cooking, melting, boiling.
