WebFeb 13, 2024 · Energy. Generally an endothermic reaction see absorption of energy from its environment ,while exothermic reaction see as system give of energy to the environment. Therefore,when energy is absorbed in process, the phenomenon called … The molecules of a solid are tightly packed. There exists a strong intermolecular force of attraction between them. To break this rigid structure, we require energy to be supplied to conduct its sublimation. Also, a solid exists at a lower energy level than a gas. Any phase transition that occurs from a lower energy level … See more As temperature rises, the vapor pressure of a substance increases. Sublimation occurs when the vapor pressure of the substance is greater than the total atmospheric pressure. And when the temperature hasn’t … See more In an endothermic process, the system absorbs heat from its surroundings to conduct the reaction. While in an exothermic process, the system releases heat into its … See more Following are the applications of the sublimation process: • Erosion and sublimation result in ablation. Ablation is the process that … See more A few examples of sublimation are as follows: • Dry Ice: Solidified carbon dioxide is known as dry ice. Dry ice transforms from solid into gaseous carbon dioxide when it comes in … See more WebSublimation: The process in which a solid substance is directly converted into a gas phase, without a change in the temperature, is said to be sublimation.
