Condensing is the process where a substance changes from a gas to a liquid. This occurs when the gas cools down, causing its molecules to lose energy and come closer together. An everyday example of condensing is when water vapor in the air forms droplets on a cold glass. In the context of science, condensing is an important part of the water cycle. It helps to create clouds as water vapor rises, cools, and condenses into tiny water droplets. This process is essential for precipitation, which replenishes water sources on Earth, supporting ecosystems and human activities.
