Specific rates of evaporation can only be measured when one knows the exact measurements of those energies and factors that bear influence upon it: air flow, temperature (of air, container, as well as actual water at time evaporation), concentration of impurities in the water, concentration of substances in the air, actual air pressure (evaporation takes less time in areas of low pressure), the actual surface area and concentration of the water to be evaporated, any known inter-molecular forces, as well as the true density of the water being measured.
All that being said, simple measurements can be made using an instrument called an "atmometer" or "evaporimeter," which can actually be fairly simply made so that a non-complex experiment can be performed to get a general rate of evaporation for your area.
The experiment requires the use of local tap water and porous filter paper, which will be used to draw the water from any measured glass cylinder into which a wick has been carefully placed. The wick can be made of any number of things- paper, cloth, string, and other similar goods that will actually allow the water to be drawn through it. As water evaporates from the surface, it will draw water from the cylinder onto the filter paper through use of the wick by simple capillary action. The more water that evaporates from the filter's surface, the more water will be drawn from the cylinder. By the taking of periodic measurements of the water that remains in the cylinder, and repeating the experiment a number of times, enough so that an average time can be formed, a rate of evaporation can be rather easily established. This rate will only be true for this one area at the time the experiment is performed, but it will give you a general idea of the rates of evaporation in this one specific area
The mass of the glass of water will remain the same if there is no evaporation or addition of any substances. The weight of the glass of water may decrease slightly due to evaporation of water over time, but this change would be very small for a short period.
The amount of water that would evaporate from 200ml next to a fire over 5 days depends on several factors, including the temperature of the fire, humidity, air circulation, and the surface area of the water. Typically, water can evaporate faster in a hot and dry environment. As a rough estimate, several milliliters to tens of milliliters could evaporate daily, potentially resulting in a total evaporation of around 50-200ml over the 5 days. However, this is highly variable and would require specific conditions to provide an accurate figure.
The water in salt pans will evaporate most quickly on hot and dry days with low humidity and intense sunlight, as these conditions enhance the evaporation process.
If the glass of water is left on the table over many days, the mass of the water will remain the same as the amount of water does not change. However, the weight of the glass of water may decrease slightly due to evaporation of the water, depending on environmental conditions like temperature and humidity.
Yes, water can still evaporate on cloudy days. While less sunlight reaches the surface, the process of evaporation can still occur due to factors like temperature and humidity. Rainfall and relative humidity may impact the rate of evaporation on cloudy days.
it is known that water evaporates even a room temperature.If you put water in a glass and set it aside for 3 days the water level decreases but if it is covered the water level remains the same. Does it mean that water did not evaporate even if the conditions are kept the same.
Just leave it for a few days and the water will evaporate, and if there was salt, you'd see it. Taste it! LOL!!
7 days
Absolutely. Water can evaporate in almost any conditions.

if there's sun there is evaporation
This depends on many factors.
The time it takes for water to evaporate depends on factors like temperature, humidity, and surface area exposed. In general, it can take anywhere from a few hours to a few days for water to completely evaporate.

No the sugar has water and the water would evaporate within the ten days
Epsom salt is a stable compound that does not easily evaporate. It can only evaporate along with water if a solution of Epsom salt and water is left to dry out, which could take days to weeks, depending on the conditions.
a few days or weeks. It might even take months depending on how hot the lamp is and how much cold water you're trying to evaporate.
