Fans help dry wet clothes by increasing air circulation, which speeds up evaporation. Although fans cool, the faster-moving air helps water molecules escape more quickly, facilitating the drying process despite not adding heat.
Examples of liquids other than water that evaporate include alcohol, acetone and gasoline. These liquids evaporate at different rates and temperatures, contributing to various applications like cleaning, fuel and industrial processes.
