Factors that affect evaporation include the concentration of the evaporating substances in air, temperature, air pressure, the rate of airflow and surface area. The heat of the sun facilitates the evaporation process, which is important in the water cycle.Continue Reading
When the air is saturated with the evaporating substance or other substances, evaporation is slow. High pressure on a water surface reduces the rate of evaporation. Storms are examples of high-pressure systems that slow down evaporation. At a high humidity, the rate of evaporation is also low.
A high rate of airflow increases evaporation. Large surface areas also facilitate evaporation. An increase in temperature facilitates evaporation by increasing the kinetic energy of the evaporating molecules. However, strong intermolecular forces or bonds reduce the rate of evaporation. This is why boiling water evaporates faster than cold water.
Water evaporating from lakes, rivers and oceans remains in the atmosphere as vapor, which affects humidity. This is why areas with large water bodies and high temperatures have high humidity. In the water cycle, evaporating water forms clouds. The clouds later release the water back to the surface of the Earth in the form of snow or rain. An evaporation equilibrium can occur in a closed area when air is fully saturated with vapor, preventing further evaporation.Learn more about Thermodynamics
Some factors that affect the pulse rate of a person include body size, medication, body position and air temperature. The normal heart rate varies from one person to another, as stated by the American Heart Association.Full Answer >
The rate at which popcorn pops depends on a number of factors including the water content of each kernel, the rate of increased temperature of the kernel and the way in which the kernel is heated: air, oil or microwave. Many experiment results have been published online with different brands and invariably different results.Full Answer >
There are numerous factors that affect pulse rate including a person's weight, body position, air temperature and medication use, according to American Heart Association. A heart rate will become elevated when a person performs physical activity, and individuals can keep track of their heart rate during exercise to closely monitor their activity level.Full Answer >
The rate of evaporation of liquid depends on the temperature of the liquid, the surface area, vapor pressure and the air movements of the surroundings of the liquid. These factors all play a part in the process.Full Answer >
