As clothes dry in a dryer, the water in the garments undergoes a process called evaporation. Evaporation is the transformation of a liquid into a gas, in this case, water turning into water vapor.
When you place wet clothes in a dryer and start the drying cycle, the machine generates heat. This heat raises the temperature inside the dryer, creating a warm and dry environment. As the warm air circulates through the clothes, it causes the water molecules within the fabric to gain energy and convert from a liquid state to a gaseous state (water vapor). This process is accelerated by the movement of the dryer drum, which helps expose more surface area of the clothes to the warm air.
The evaporated water vapor is then expelled from the dryer through the venting system. Dryers are equipped with vents that allow the moist air to escape from the machine and be released outside or through a designated venting system. This venting process helps remove the water vapor from the drying clothes, ensuring they dry efficiently.
It's important to note that not all of the water present in the wet clothes evaporates during the drying process. Some residual moisture may remain, especially in thicker fabrics or in garments with multiple layers. Additionally, the effectiveness of the dryer's ventilation system and the drying time can also influence the amount of water evaporated.
