Which will evaporate faster?
Hey....not every body is chemistry inclined.... so I'll tell you 9. is B because whenever something dissolves in water the boiling point goes up (Generally Speaking).....think the antifreeze in your car...it is there to stop boiling....and freezing 10.D ...first of all the other answers are ridiculous....the size of the chrystals don't matter because they will dissolve anyways......If you cool the water less sugar will dissolve....when you wash your hands you use hot water to dissolve whatevers on your hands---not cold.....
Can moonlight evaporate water?
You don't need ANY light to evaporate water. All you need is very dry air above the water. Once the air above the water becomes saturated (i.e., 100% relative humidity), the water will cease evaporating. If you have the water in a sealed jar with air space above the water, it will evaporate only until the air in the jar is saturated with water and then the water level will remain constant.
Does water evaporate faster in night than day?
In the day there is the sun which provides heat to increase the temprature allowing a faster evaporation.. It also reduces the air humidity allowing more evaporation to take place However, during the night the temprature drops so evaporation is reduced. The humidity is usually reletively higher during the night. Hope this Helps! Good Luck =)
Approximately how much water will evaporate overnight from a standing bathtub full of hot water?
Assuming a room temperature of about 72 Fahrenheit, a surface area of about 10 square feet, and air movement at 1 mile per hour, it would be around 1/3 gallon per day with room temperature water. If you divide a 1/3 gallon by 3 (8 hours overnight being 1/3 of a day), you get about 1/9th of a gallon, which is a little over 14 fluid ounces. You state the tub is filled with hot water, but it would cool fairly quickly unless you kept it heated somehow. If you did keep it heated, then the evaporation would be more. Also, if the air in the room is dead, almost no movement at all, then the evaporation would be much less, as little as 1.5 ounces (3 tablespoons) of water in 8 hours. If you want to figure this out with greater precision, go to a website with pool evaporation formulas and plug in the exact numbers. You will have to figure out how quickly the water cools to room temperature, because the water vapor pressure is highly dependent on the temperature. Anyway, I have no idea why you want to know this, but I’m just messing around with the math and have no special expertise.
Would 50mL of water completely evaporate overnight?
Yes, I realize there are many other factors to consider, but I'm setting up a lab and I need to know if I leave it overnight if it will all be gone. It will be in a graduated cylinder and in a classroom. About how long do you think it will take to completely evaporate?
How much water evaporates from CaCl2 solution left out overnight?
you can calculate the volume of water evaporated by finding the voume of concentrted solution left by using molarity equation; M1V1=M2V2 0.275x230=1.73xV2 V2=36.5 so water evaporated is 230-36.5=193.5 ml
How do you get water to evaporate faster?
Put it under a vacuum.
If I let a glass of water next to my bed, will part of it evaporate overnight? If so, to what extent?
Yes, some will evaporate. The amount depends on the temperature of the water, the humidity of the room and the air circulation in the room. The hotter the water the easier some water molecules at the surface of the water will have enough energy to evaporate. You see this effect when very hot but not boiling water is in a glass and you see some smoke like mist rising from the glass especially when the room is cold.Similarly the less humid the room is and the greater the air circulation in the room the faster evaporation occurs. That's why sweat evaporates faster when you enter an air-conditioned room and you turn on the fan to dry the floor after mopping it.Try it tonight with a glass of water, just make sure the glass doesn't topple.
Water Cycle operates at night?
Hi everyone. For my science homework I was given a question about the water cycle to do. It doesn't make sense to me so maybe you guys could help me! Here's the question: Part of the water cycle does not operate at night. What part is it and why? Any answers would be appreciated! Thanks in advance!! Twinkle Toes xx
Is there an evaporation at night? Where does the energy come from?
I’m assuming you mean evaporation of water? Yes there is evaporation at night. Water doesn’t have to be at 100°C to evaporate. The rate of evaporation may slow down when it’s cooler, but it will happen. All you need is the right combination of temperature, pressure and humidity. As for the energy, the heat comes from the sun. Heat can be reradiated from the ground during the night, or carried by air currents.
