Why are steam burns worse than hot water burns?

The temp. between hot water and steam is a big difference. Say that steam is at 400 degrees F and hot water is 180 degrees F, steam will boil your hand faster then hot water.

cold water boils faster for the same reason that hot water freezes faster. I don't know what that reason is.

actually, water heats up and cools off slower than soil.  Water takes more energy to heat up and once it gets the energy it takes time for it to lose it. Citys near water have a more constant temp. than cities that arent near water. It can be 80 one morning in Kansas then 10 degrees that night

If the element is bad it will take forever to heat hot water back up. I would check that first before you put alot of money into it. Hope this helps.

Avoid using hot water on that area, it will dry your skin out more.  Apply Aloe Vera gel or lotion to the burnseveral times a day.  Do not use any oil or petroleum based products on a sunburn.  Stay out of the sun and allow your body to heal.  If the burn doesn't get better or you notice any unusual growths caused by the sunburn make an appointment with your doctor.  Next time use sunscreen that protects against UVA and UVB rays.  Protect your skin, good luck to you.

This depends on what you wanted in the colorimeter in the first place, are you looking at temperature change rates going up, or down?  Either way, if you mix the two, it will skew the results of your experiment.  Hot water, even at 100 C still may have a lot of ability to absorb latent heat of vaporization before it becomes steam.  Your temperature curve will slow significantly or even flatline for a while if you are increasing temperature.  If you are decreasing temperature, hot water has already lost most of the latent heat of vaporization, it has already become liquid, this will impact your results.

1. microwaves heat water faster than boiling it over a heat source.\n\n2. microwaves have a more direct effect on an atom, since the energy is transferred directly form the MW to the atom, unlike the boiling water where it is transferred from heat source to water to the thing (w/ enzymes). the longer path means longer time.\n\n3. since the atoms (or molecules for enzymes) directly interact with the MWs, they are more likely to be destroyed than when boiling water is used. Hence the shorter time to ensure deactivation, and not destruction, is achieved

well firstly you are using less electricity and also the steam is not polluting the atmosphere directly. apart from that there aren't really any other advantages i can think of

Nothing.  Except have a lower water volume due to warmer water molecules converting to gas.  However, the warmer water may have an efffect on the plants you are studying.  If you water a plant with hot water it may kill the plant.

Yes, in some specific circumstances, hotter water freezes faster than colder water.  All explanations are still hypotheses and there is no fully proven explanation yet for why.  It's known as the Mpemba effect.

Once something has already burned, it will not burn again. Water is the result of hydrogen burning.

If the iron is hotter that 212F, then a thin layer portion nearest the iron may get temporarily superheated. In large commercial generators, the steam is heated to 1000F before being sent to the turbine. This may happen in more than one cycle. Main steam is sent at 1000F(called superheated), goes through the first section of the turbine, returns to the boiler, is raise back to 1025 (called reheated), and returns to the turbine.

well i guess it would be anything under the bloods boiling point which is approx. 0.158 degrees centigrade. but of course it might still burn..i myself like hot water so i've bathed in water that had smoke rising from it and my skin turned red...is that hot or what! lol

It would depend on the amounts (mass) of the water.\n\nedit:\nThe specific heat of water is not 1 [artless_man], it is 1 calorie per gram degress celcius, the units make all the difference.  Notice the lower case c in calorie.\nA "better" specific heat of water, using metric units, is 4.186 J / (gram * degree celsius).\n\nHowever, for this problem, you dont even need to know the specifc heats since both substances are water.

They send it to cooling towers to turn the steam back into water, so they can take advantage, once again, of the mechanical energy involved in water expanding into steam.  Water expands a lot turning into steam, but when steam just turns into even hotter steam, the pressure increases, but not that much.\n\nSure they could be even more efficient by finding a good use for the extra heat, but that would be a bunch more machinery.

When you boil something, and there is still water in the pan, the temperature can be no higher than about 100C.  When you put this pan in water, it cools so quickly that you will not see steaming.\n\nWhen you fry something, the pan can easily reach two to four times higher temperatures.  There will be so much heat in the pan, because of the higher temperature, that it will cause flash steaming when you immerse it in water.  The steaming will stop when the pan temperature drops below the boiling point of water.
