If milk is used instead of water in the evaporation activity, the process would still occur, but at a slower rate. This is because milk contains fats, proteins, and other components that influence evaporation. The presence of these substances creates a thicker liquid, which hinders the escape of water molecules into the air compared to pure water. Additionally, milk may leave behind residues as it evaporates, unlike water, which evaporates more cleanly, further affecting the overall process.
