Population Change is going to occur because of many reasons
1) theory in economics (Malthus Theory): when population increased to a large amount than any natural disaster occur to balanced it.
2) Bio theory (Natural Selection): with the new technologies habits of man are changing that results in change in birth/death rate, immunization etc.
3) Food habits are also changing: that causes less immunization and rapid spread of diseases.
4) Wars: as today's mass destructive weapons results in large reduction of population.

What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
