What is it called when water takes a lot of heat to evaporate it?
You think probable to an endothermic process.
How could salt be separated from water a coffee filter freeze heat to evaporate or add ice?
Heat to evaporate. This is how a lot of people used to get sea salt; they would dig pits on the beach and let the sea water evaporate. Also, please use commas in your questions, it makes them a lot easier to read!
Do olive oil and vinegar and evaporate?
Vinegar contains a lot of water, which will evaporate. Oils evaporate VERY slowly.
Why water doesn't evaporate on hot humid day?
Because humidity means there is a lot of water vapor in the air, and thus, water cannot evaporate, as there is no room for it in the air.
Does the temp affect how light bulbs evaporate water?
The light bulb increases the temperature, and the higher the temperature, the faster evaporation occurs. The light bulb itself doesn't evaporate water. If you're using the old incandescent light bulbs, they will give off a lot more heat, and evaporate more water than an energy-saving bulb. It also depends on the distance between the bulb and the water, the surface area, mass of water, and time.
Does higher boiling point evaporate faster?
Evaporation and boiling are the same process, liquid water is converted to water vapour. To convert from liquid to gas the water molecules have to absorb heat. The rapidly the heat is supplied, the faster the liquid water changes to a gas. In evaporation this heat comes from the air the water is exposed to, the surface the water sits on and the heat already in the water (hot water cools as it evaporates). This process is relatively slow compared to boiling water where a lot of heat is being put into the system by the stove or hot plate. It takes the same amount of heat to boil or evaporate the same amount of water. Boiling provides this heat much more quickly. Therefore boiling water evaporates much more quickly.
Name a characteristic property of water?
Water requires a lot of energy to raise its structure and to evaporate.
Does a 60 watt light bulb evaporate water faster than the sun?
Faster than ambient left alone? If compare to open air then it is faster with extra heat source of 100 Watt. If it had twice the bulb then it is faster than 1 bulb. Light bulb is the energy source and evaporation require energy. Provide extra energy help speed up evaporation.
How does chemical bonding between water molecules make water a valuable coolant in organisms?
Hydrogen bonding occurs between adjacent water molecules. This is a strong intermolecular force. Water hence requires a lot of energy to change from a liquid to a gas. The evaporation of water hence has a cooling effect as a small amount of water requires a lot of energy to evaporate, removing heat in the process.
Does water evaporate faster in a dark glass or clear glass?
It depends on how much light is shining on the glass. If there is a lot, then the water in the dark glass will evaporate faster because the temperature will be higher. If there is no light, then it does not matter.
What happens to ocean water that does not evaporate?
The water that doesn't evaporate into vapor stays in the ocean as liquid water. The oceans have a lot of liquid water. Over time, ocean water is always evaporating and turning into rain and comes back to the ocean; but the salts and minerals carried into the sea from rivers never evaporate. They stay dissolved in the ocean waters and make it saltier and saltier.
What heat energy do you feel from boiling water?
A lot.
