Question

The process of changing of water into its vapour below its boiling point is called _________________.

Answer 1

Evaporation:

• Evaporation is a process in which a liquid changes into a vapor.
• It occurs below its boiling point.
• For example, the evaporation of water occurs below its boiling point($100°\mathrm{C}$).

Evaporation depends upon following factors:

• Temperature: As the temperature increases the process of evaporation also increases.
• Surface area: As surface area increases, evaporation rate increases as well.
• Wind: As the speed of moving air increases, the evaporation also increases.
• Humidity: As the water vapors increase in an atmosphere, the evaporation also decreases.

Thus the process of changing water into its vapor is called evaporation.
