During what process do gas molecules lose energy to form liquid?

The process in which gas molecules lose energy to form a liquid is known as condensation. During condensation, molecules in the gas phase encounter conditions that cause them to lose kinetic energy, often when they cool down. As the energy decreases, the attractive forces between the molecules become more significant, allowing them to come together and transition into the liquid state.

This process is fundamental in various natural and engineered systems, such as the formation of dew on grass or the condensation that occurs in air conditioning systems. Understanding condensation is crucial in fields such as meteorology and physical science, as it plays a key role in the water cycle and the behavior of gases.
