Cooling processes refer to methods that reduce the temperature of a substance or environment. Common examples include evaporative cooling, where liquid turns into vapor and absorbs heat, and conduction, where heat transfers from a hotter object to a cooler one. These processes are essential in various applications, from air conditioning systems to industrial cooling. Another important cooling process is radiative cooling, where objects lose heat by emitting infrared radiation. This phenomenon is often observed at night when surfaces cool down after absorbing heat during the day. Understanding these processes is crucial for energy efficiency and temperature regulation in both natural and engineered systems.
