How long will a cup of water take to evaporate at room temperature?
open or close will 10 hours
If you store an ordinary water in room temperature 17 to 25 C for very long time like more than two years Will that ordinary hard straight from the pipe water rot or become undrinkable?
Yes, if you place a cupful of water and a cupful of gasoline in a sunny window. Both cups have the same volume of liquid in them. 24 hours later you observe that both cups have less liquid in them, but there is less gasoline than water, why? Because gasoline, or petrol, is supposed to evaporate in room temperature, gas does not freeze but it can evaporate slower by colder temperature.
Does is a liquid at room temperature, raising the temperature will certainly not turn it into a solid. Think about water. Raising the temperature of water will evaporate it and make it a gas. The only way to increase the temperature of something to make it into a solid is to also greatly increase the pressure.
lets say you have a cup of water that is cold. when the air at roomtemperature hits the glass (look below) the air condenses because it is cold. this forms little drops on the outside of cup. this continues till the water is at room temperature them the water proceeds to evaporate. (When a temperature is warm molecules spread out and when they are cold they condense.)
Yes. If the chloroform is in a confined space, only a small fraction of it will evaporate, but if gas circulation sweeps away the chloroform vapor from contact with the liquid chloroform and there is an adequate supply of heat from the environment to maintain room temperature, eventually the entire sample will evaporate.
Root vegetables can be stored at room temperature not exceeding 24 C as the water content tends to evaporate shrinking the vegetable to make the skin tough. High humidity & temperature can spoil the root vegetables. Tubers like yam have thick skin and can be preserved for a long time. Tubers with thin skin cannot be stored for long time in room temperature It can be stored in a net bag in a refrigerator.
There are other factors to consider. Outside temperature. If you are at the artic in below zero weather the water would freeze before if evaporates. Altitude. Higher altitude on a mountain gives a lower boiling point, ant at the same temperature, would evaporate faster. Humidity. High humidity will slow the rate of evaporation. Size of the cup. A measuring cup is 8 ounces. A tea cup is less, recent cup sizes for coffee have increased…
Untill a balance between the liquid - let's say water - and the substance surrounding it - let's say the air - is reached. The factors influencing evaporation - when the molecules of water leave the liquid and 'fly' with the molecules of air - are the relative air humidity, pressure, temperature, (air and water movement, and so on). Water will evaporate until air humidityl allow it - that is until a moment when a…
