The rate of evaporation of liquid does not depend upon-

Evaporation is a surface phenomenon where molecules at the liquid's surface gain enough kinetic energy to escape into the gaseous state. The rate of evaporation is determined by environmental and physical factors rather than the total quantity of the liquid. Key factors include temperature, as higher temperatures increase the kinetic energy of molecules [2]; surface area, because evaporation occurs only at the surface, meaning a larger exposed area facilitates more molecules escaping [1]; and humidity, as air saturated with water vapor (high relative humidity) has less capacity to absorb additional moisture, thereby slowing the process [1]. While the total mass of a liquid determines how long it will take for the entire volume to evaporate, it does not influence the 'rate' (speed per unit area) at which the process occurs. Other influencing factors include wind speed and atmospheric pressure [1].
