The atoms in a chemical reaction are responsible for the mass energy temperature explosion

Mass

Mass is something that can be converted into energy according to the Eisenstein formula. So if there is no mass there is no energy. Similarly the mass of atoms makes them matter as we say that matter is something having mass and occupy space. In the same way temperature is also a quantity which is produced by collision of atoms. In short mass of matter is responsible for energy, temperature and explosion.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
