an endothermic reaction

an exothermic reaction

an endothermic reaction

an exothermic reaction

endothermic process because the reactant is dissolved in a liquid thus changing its state

endothermic process as the process breaks the bonds of ammonium nitrate into ammonium and nitrate separately

exothermic process as there is the release of heat during the process of breaking the bonds of ammonium nitrate

exothermic process as the process forms the bonds of ammonium nitrate

Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.

law of thermodynamics states that the entropy of any isolated system always increases.

entropy of a system approaches a constant value as the temperature approaches absolute zero.
