Steam. It's hotter than boiling water to begin with (more energy has been imparted to it allowing it to vaporize), and when it comes in contact with you, it gives up that energy to your skin, transforming back into boiling water (which can only get up to 100 degrees Celsius), which gives up more energy into your skin until the water is back to a reasonable temperature.

Not that Wiki is a perfect source and some University will no longer allow it as a source so you would always get additional verification especially if you are writing a thesis.
hot water, though wont you have to say why? because hot steam is just the part so hot it evaporated, wait then hot steam must be hotter :l ergh my brain, read my sig link what i look like to loose your brain to
Come on, if you don't know the answer then you don't deserve to pass the subject. Steam is super-heated water, so if the water was able to cause the same burns as steam, it would be steam (or maybe really cold ice?).

well the point is hot water carrys much more energy than steam becasue of its specfic heat at liquid>solid>gas for some reason. I been studying thermochemistry ftw.
well here's where logic and expereince sort of mix up.
Logically steam would burn worse since it's technically evaporated water. My understanding would be higher tempurature worse burn.
From my experience though steam doesn't burn near as bad as water. For example if I cover a boiling pot of water, and then lift the lid the steam isn't going to burn me as bad as sticking my hand in the boiling water. You can argue that I'm not touching as many water particles with steam than boiling water, or that the steam is spread out so much it's cools much faster.
The point is how much energy each one holds at a certain volume holds. boiling water holds much more energy than steam at the same volume thats why if you put ur hand in a jet of steam the same amount that you put ur hand in a pot of boiling water the one which ur hand was in the boiling water is much more damaged than the one in the steam becasue of the energy capacitys per volume.

exactly thats why steam holds less energy even tho it can attain a higher temperature for what it has water holds a ton more energy to burn ur hand.

That was my thinking too. When the kettle boils and the steam comes out, it doesn't really hurt to pass you hand though it. But if that steam was a stream of boiling water...I don't think I'd pass my hand through that.
Sure the steam may be hotter, but it's so much more dispersed, you don't notice.
Hot steam is going to be much hotter than hot water by virtue of the steam being able to exceed 100 degrees Celsius. Hot steam can be as hot as 1000 degrees. The question isn't very specific.
But a high pressure blast of steam from a pipe can burn you much worse than boiling water.

You're right, the question isn't very specific. It really depends on how concentrated said steam is in order to determine how hot it will be. Has anyone ever stuck there face a few inches over a pot of boiling water and let the steam sooth your pores? I can hold my face there for much longer than if I were to submerge it into the water itself, I asure you.

I think the kid meant the kind of steam you would encounter in everyday life. Not at a eletric plant. The steam in everyday life would contain much less energy per volume than the same volume of boiling water of the same tempurature. Also has to due with the specfic heat of the states of water to get steam to 1k and how much energy that compares to pressurized water at 1k c.
