Endothermic reactions are reactions that proceed by the absorption of heat (energy) while exothermic reactions involve a release of energy.
a) Formation of frost on a car window in winter is an exothermic process as heat is liberated when liquid water freezes to form crystals
b) Formation of water condensate on a glass of ice water is an endothermic reaction since heat is absorbed by the cold water from the glass container thereby cooling it.
c) A decrease in the temperature as ammonium nitrate is added to water is an endothermic reaction
Answer: The spontaneous intermingling of atoms among different substances is accomplished by diffusion.
Explanation:
Diffusion means to spread out. In diffusion, the molecules or atoms move from a region of high concentration to low concentration.
In other words, we can say that the spontaneous intermingling of atoms among different substances is accomplished by diffusion. Diffusion depends on the random walk of an atom or molecule.
Molecular kinetic energy is the energy of a gas at ordinary temperature in which the atoms or molecules are in rapid motion.
Displacement is the property in which a reactive element displaces less reactive element from its position.
Condensation is the process of changing water vapor into liquid.
Thus, it can be concluded that the spontaneous intermingling of atoms among different substances is accomplished by diffusion.

Answer: As for vapor pressure being higher at higher temperatures, when the temperature of a liquid is raised, the added energy in the liquid gives the molecules more energy and they have greater ability to escape the liquid phase and go into the gaseous phase.
