Which will produce more severe effect water at 100°c or steam at 100'c ?
Answers
Even at the same temperature, steam and boiling water don’t contain the same amount of energy. Water has a high heat of vaporization—it takes 40 kilojoules per mole to get water to boil into steam after it reaches boiling temperature, five times the energy needed to bring it from freezing to boiling temperature.
This is because once you get water to the boiling temperature, you still must overcome the relatively strong hydrogen bonds that hold it together as a liquid.This also means that when steam hits your flesh and condenses, it releases the same heat of vaporization—five times the energy needed to bring freezing water to a boil—so it causes far more damage.
Besides that, it’s wrong to assume that steam and boiling water have the same temperature. At atmospheric pressure, steam can exist at temperatures much, much higher than the boiling point, and under pressure, can be hotter still. They used to do a demo at a nuclear power plant in which a piece of insulation is removed from a superheated steam line. When a straw broom is held up to the pipe, it bursts into flames due to radiated heat. Such steam is far, far hotter than boiling water, and is instantly fatal to any human.
Answer:
steam at 100'C
Explanation:
because steam at 100'C has more amount of heat than water at 100'C all this happens due to latent heat of fusion
