Placing water in containers increases evaporation rate.
If I increase the height from which a drop of water is released, then the diameter of the splash increases.
If I increase the temperature of water, then the dissolving time of salt in water will decrease. This is due to the fact that the molecules of hot water move quicker.
If I place water in containers with different surface areas, then the water will evaporate faster from the container with the greatest surface area. This is true because I know.
