Cooking is my favourite and bathroom the least. Dusting pah - you cant tell the difference between a quarter of an inch of dust and half an inch!

Ah and to look at some of your other ideas. Water is resistant to being heated because it can hold a lot of energy so it takes a lot of energy to heat, that is probably what got you that idea . To illlustrate the example: it takes 4.2 joules to raise 1 g of water by 1 degree, so if you want to boil 2 litres (I will put this in a term the 'international' audience can understand later ), starting at 25 degrees C and ending at 100, that will be 2000g of water you want to raise by 75 at a price of 4.2 per gram. 2000x75x4.2 = 630000 J! or 150000 calories. Thats 13.3% of your recommended (UK) daily allowance of energy you can eat. Its about 40g of fruit and nut dairy milk chocolate . If you boiled a whole ocean (we'll overlook the ecological impact) my explanation above would still be the case, it would just be losing a lot more high energy molecules and the average would still drop too far without any heating to replace them. Possibly it would stay heated a little longer because there is more of it to insulate the rest, but high energy molecules would still be escaping from the surface . What type of cooker do you have? If it is electric, then the reason the pot does that when you just turn off the heat is because the electric heat does not vanish instantly - turn on a ring, leave it to heat up, turn it off and hold your hand over it. It should still be hot. This means that the ring is still helping to produce the high energy water molecules that cause the water to boil. Though this time it has a limited supply of energy, which is why it does not last forever and only prolongs the boiling a little while. If it is a gas or other 'instant off' type heat.. I am not entirely sure. Perhaps the metal you are standing the pan on is heated a little (though this would be a very minor effect I think). I think the most likely explanation is that by not touching and moving the pan, you are not 'disturbing' the 'not quite high enough' energy water molecules and arent therefore knocking *just* enough energy into them to make them decide to move and thus arent contributing towards the drop towards average.

Your only other idea is correct. The water will be *Exactly* at the boiling point, so when no more energy is being supplied to make Energy Loss = Energy Gain (energy loss from steam, heat, etc and energy gain from the heating) it instantly has no more energy to stay at a rolling boil. Thats the simple explanation. To get a bit more complicated we need to look at what is actually happening when we boil water. Have you ever noticed that a rolling boil is not an 'on/off' process? It arrives there gradually doesnt it? The process of heating is the process of adding more energy to the molecules of whatever you are heating, in this case water. The steam coming from the water is actually the water molecules with the highest energy because they have the energy to 'escape' the water more easily. Ok, so think about the water now you know that there are different levels of molecule energy within it - its a 'bell-curve' - most water molecules will be at a certain average point. When the heat is still being applied, the escaping high energy molecules are being replaced at the same rate they are being lost if it is at a rolling boil. But if the heat is removed, the high energy molecules are still escaping, and they are not being replaced. So the highest energy molecules have been lost, and there are less molecules at an extremely high energy - this leaves the molecules at 'average' and 'low' energies, this isnt enough to keep the water boiling. Partly because the vigorous boiling you see is caused by the high energy molecules escaping from the bottom of the pan and disturbing the water, and partly because the temperature has dropped towards the previous average enough to take it away from the boiling point. Pressure is also an important issue, but only in the context of what ive just explained above - a substance boils when its 'vapour pressure' equals atmospheric pressure. Vapour pressure is just a chemical term meaning how much pressure the substance exerts on it's environment, it goes up when that substance is heated. So from this you can see that if atmospheric pressure goes down, so does boiling point. Keeping the lid on the pan probably lowers the pressure slightly, because it is holding in 'low pressure' (low density) steam and keeping high pressure atmosphere out, but the most important effect is mitigating the loss of those highly energetic molecules I was talking about earlier - its harder for them to escape if the air above them is crowded with other escapees. I hope this is ok .

Well for such an odd topic this has been very informative . Given that since about the middle of the 16th century the british isles have been heavily involved in colonialism.. the original 'true british' food probably isnt particularly interesting since there was never any need to develop any. But I suspect that the 16th century peasants food from your country is not all that interesting either . We eat food from around the world as a matter of routine. I used to bash the egg against something, but I found that I wanted more control and precision! So at first I used the spoon to make the hole, then moved on to doing all the work with it . Interesting how for such a basic task there is a big disparity in the way it is done.

Sorry, Im not sure that makes sense. You dont use sites like that because.. you wont post nude pics of yourself and arent impressionable? I dont think you can generalise about social networking, not everybody who uses it is a predator/teen/immature. .

When I peel a hard-boiled egg, I smash a small hole in the wider end with a spoon, and then put the spoon through the hole i made and under the shell, enabling me to just pull the shell off and leave the egg intact. Im curious, I am alone among my friends in using this technique, which I believe to be faster and less damaging on the eggs. So I put it to you, dear readers - who uses the same technique? (I think the poll choices cover all the possible options)

[dkstories] Dreams of a Father
Aeroplane replied to NaperVic's topic in Promoted Author Discussion Forum
Ah, when I said magic I was talking about the torpedoes that Garret pulled out of his sleeve from nowhere. . Drug induced hallucinations I can deal with . There is one explanation for Garret doing something wholly out of character (we've seen what he thinks of what happened on Calos) - building planet busting weapons, and that is that he already knew about these new aliens. This I would accept as sufficient motive for suddenly having these magic torpedoes . Is the wormhole that he didnt want closed a wormhole which leads to the place these aliens came from? Has it always been there? There have been a lot of wormholes recently, its hard to keep track of them all . -
[dkstories] Dreams of a Father
Aeroplane replied to NaperVic's topic in Promoted Author Discussion Forum
I do like this series, but this new 'twist' seems a bit too 'convenient' to be believable. 'Current problem solved, need to introduce a new plot element or the series will be bumbling along.' 'Ah here it is, some more aliens.. Which I happen to have the solution to packed neatly in my handbag of tricks.' Got to be careful with using magic, instant problem solves are no fun. . Would have been nicer and less.. unexpected to the point of disbelief.. if there were hints in the previous 5 or so chapters instead of just a spontanous event. -
[DomLuka] Chey, how do you pronounce it?
Aeroplane replied to NaperVic's topic in Promoted Author Discussion Forum
I go for neither option. I pronounce it phonetically using the 'Sh' from 'Show' and the 'ey' from 'Hey'. Though I dont know how you staters pronounce those words either. -
Some things Ive learnt: Paying bills, while novel, is in no way fun. Dont have a relationship with people who have major issues. If you do, dont hold unrealistic expectations - you probably cant 'cure' them. Be proactive at everything. Try not to let your higher education institute screw you over somehow - theyre a company, not a schooling establishment in the sense youre probably used to. If you want something done properly, you have to do it yourself. Trying to cut through university red tape is no more fun than paying bills. Those are mostly negative though.. hmm.. Learning that I can live on my own and mostly off my own means has been an eye opener for me. It feels damn good. Other people can be worth investing your heart into.

Lets have a chat then. I have had my hair cut and dyed recently.. red on the fringe . Whats your hair like?

I think there is a more simple explanation than some sort of primal urge to create. Boredom is a major force that drives almost every aspect of our lives or rather; escaping from boredom by doing something is. People get bored easily. QED. Its good that they do, though, because it helps more people elevate themselves above base boredom! So thanks!

I hate it when people gravedig threads (only kidding Vic ) I hate it when people blame you for something you are not responsible for. I hate that I know that sometimes I consider double standards acceptable. I hate it when you know who they should be blaming but theyre too blind to see it! I hate it that im the only one being blamed when there are at least 3 others

I am a big fan of groan-worthy puns, so on Sunday, I created a facebook event to invite people to my flat for a party. I called it '2D Party (a flat party)'. What are the worst puns you have graced the world with?

As best as I can guess, a literal translation would be 'In wine, truth' or something like that . As for what to do. Hm. Get drunk with him again, have a drunken conversation with him about what happened and make sure you remember it. Also because it was a three way kiss it might have just been novelty value.. easier to do something like that when its less personal ;p.
