What phase change requires to lose energy
Answer (1)
An exothermic process is one in which a substance must lose energy in order to undergo a phase change. Particles must slow down and approach each other during a substance's transition from gas to liquid or liquid to solid to become more "chill" and ordered, releasing some energy, typically as heat.The following phase transitions necessitate an energy loss:FreezingThe process of condensationDepositionRecombinationThe concept of a liquid and a solid is similar to the process of a gas turning into a solid. When a gas loses energy, it loses momentum, causing it to lose its momentum and release heat. This concept applies to both liquid and gas transformations.Key Points:The substance becomes more structured (gas to liquid to solid).Energy is given off to the surroundings.The particles in the substance move less.The forces holding the particles together become stronger.Freezing water, condensation of steam, frost forming.The more organized and less active the particles are, the less energy they have, and the extra energy has to go somewhere—it gets released.
