What best describes evaporation?

  1. The process in which liquid turns into solid

  2. The process where gas turns into liquid

  3. The process of molecules escaping from the liquid phase to gas phase

  4. The process of dissolving a solid into a liquid

The correct answer is: The process of molecules escaping from the liquid phase to gas phase

Evaporation is best described as the process of molecules escaping from the liquid phase to the gas phase. This phenomenon occurs at the surface of a liquid, where individual molecules gain enough energy to overcome intermolecular forces and transition into a gaseous state. Factors such as temperature, surface area, and air movement can influence the rate of evaporation. Understanding evaporation is important in various fields, including nursing, as it can relate to patient care, such as monitoring fluid loss through perspiration or wound healing. The other processes listed, such as phase changes to solid or liquid, and the dissolving of solids, describe different physical changes and do not accurately define what evaporation is.
