The correct answer is option A, that is, the energy release decreases the molecular motion and the kinetic energy of the substance.
When a substance discharges energy, it signifies that the energy of the molecules is now being transferred into the substance with whom it comes in contact with or into the atmosphere. Thus, at the time of the discharge of energy, the motion of molecules diminishes and as a consequence, the kinetic energy of the molecules will reduce.
Therefore, it can be concluded that for a substance the energy discharged diminishes the molecular motion and the kinetic energy of the substance.
D, obviously. All living things are made of one or more cells, therefore non-living things aren’t made of cells
Answer:
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
