The process of changing a liquid into a gas is known as evaporation or boiling, depending on the context. Evaporation occurs at any temperature when molecules at the surface of a liquid gain enough energy to break free and escape into the air. This process is vital in nature, contributing to the water cycle and climate regulation. On the other hand, boiling is a specific phase change that occurs when a liquid reaches its boiling point, resulting in the rapid formation of gas bubbles throughout the liquid. Both processes illustrate the transition between states of matter and are essential in numerous scientific and practical applications.
