What is the black stuff that is fromed?

oh ok. Thanx!

What's an oleum stage?

dave, what is the solid formed after you evaporate all the water in the acid?

to add on to that, all you are doing is collecting the condensed water in a sponge. Exactly what you said not to do!

Correction' date=' not [i']all[/i] the water. If you do, then you end up with a solid. Just make note of that. You let lots of water evaporate, but not all!

To add on to that, it is the main reason why diffusion takes place. The oxygen can pass across a damp surface (water content in it) to reach the red blood cells.

hmmm.... how long will it be before it gets fixed?

The link is still there, but nothing in it!

For who? The people making the money? or the people using it? It really depends! For the people making the tar and all that, the eneven system is better becase every few years, they are sure to make money. But, for the people using them, the autobahn system is better because it spares them the harassment. It all depends on who's point of view

lol! I think the science forums seem to be getting of the subject!

What's that bit for???

Well, we first have to answer the question "Does light have mass?" Then work out from there! Ok sorry! MY bad!

I don't think that would be of a very high probablilty! Mooeypoo would have noticed it. The food not getting heated up!

so, if you use the energy stored into the reservoir, you basically use the energy from the light, decreasing it. This leads us back to:

But isn't a reservoir a thing to store something for later use?

well it can't if u think about it. The second u start to use up the energy, then, it disappears. This is all according to the law of conservation of energy!

One thing. I don't think you would be able to see the light, therefore, prove that it works, because if u did, then, the energy would be lost. That should already answer the question about the dark room. If it is 100% reflective inside, then, it would appear black in a dark room! {edit} Correct me if i am wrong guys. I am just putting my knowledge to test here

good point!

they usually buy it off Philip & Harris or Wyvern. These are companies that sell equipment for labs

its quite stable, no real crashing or anything. The only problem is that it isn't very compatibe with Win XP, you need to run in compatibility mode, and use different software to hear sounds and all that (that is, if it is a game) Actually, it does have one. It is the command prompt. Its like a version of dos, but based on Win XP. Although, its not like the real DOS

yeah! Quite efficient!

i'll third that

In my opinion, i think if you want to be able to get energy out of the perpetual motion, energy would need to go against the law of conservation. This is because, it is impossible to keep the machine running AND take energy out of it
