Evaporation of Water from an Open Beaker: Spontaneous and Endothermic Process
Evaporation is a process in which a liquid substance changes into a gaseous state by overcoming the intermolecular forces holding the liquid together. When water is placed in an open beaker, it can evaporate over time due to the movement of its molecules.
Spontaneous Process:
A spontaneous process refers to a process that occurs naturally without any external intervention. In the case of water evaporation from an open beaker, it is a spontaneous process because it can occur on its own without the need for external factors.
Endothermic Process:
An endothermic process is a process that absorbs heat from its surroundings. Water evaporation is an endothermic process because it requires energy in the form of heat to break the intermolecular forces between water molecules and convert them into vapor.
Explanation:
When water is exposed to the atmosphere in an open beaker, the kinetic energy of the water molecules increases due to the ambient temperature. As a result, some water molecules gain enough energy to overcome the intermolecular forces of attraction and escape into the atmosphere as vapor.
During the process of evaporation, the water molecules that leave the liquid phase take away energy from the remaining water molecules. This results in a decrease in the average kinetic energy and temperature of the remaining liquid. Therefore, evaporation is an endothermic process as it absorbs heat from the surroundings, causing a cooling effect.
The evaporation process continues until the rate of evaporation becomes equal to the rate of condensation, resulting in an equilibrium state where the number of water molecules entering the vapor phase is equal to the number returning to the liquid phase.
In conclusion, the correct statement about the process of evaporation of water from an open beaker is that it is a spontaneous and endothermic process. It occurs naturally without external intervention and requires the absorption of heat energy from the surroundings.
