Same question about water boiling argument differently put!?!
Same question about water boiling argument differently put!?
Re-asking this question as I don't think I was clear before.
My wife and I are having a disagreement on whether re-boiling a kettle removes more oxygen from it.
Regardless of whether the water is used to make a hot drink or not,
will more oxygen be removed from the water if it is re-boiled?
Oh, and thank you irishgirl - my wife and I do have a fantastic marriage thanks :~) this is about all we argue about (if you can call it an argument)
Answers:
boiling does't remove oxygen from water , it removes water from water (chemical symbol H2O) which contains oxygen.
The water that is left behind is higher in concentration in minerals and impurities because they do not evaporate.
Distilation (creating pure water) is the reformation of water from steam vapor.
I herd it does..... but i always throw away water that has been sat there for a while anyway. Did you notice that tea tastes better the 1st time it is boiled and crappy after that?! ( how sad am i!)
Yes - it does remove oxygen. This is why any good cup of tea is made from freshly drawn and boiled water - the oxygen in the water aids the brewing process, if it is re-boiled water there is less oxygen and you do not get as good a brew.
You didn't say which side of the argument you were on? Hope you win!
When you boil the water, the only thing that evaporates is water molecules. The boilig doesn't disassociate the molecular bonding of water.
The reason the water tastes bad when you reboil the water is that because some water has escaped as vapor and the minerals and other additives in the water are concentrated causing the water to taste worse. If you use distilled water, this won't happen.
Logically I would say yes simply because you have water left to boil.
I believe the chemical symbol to be H2O.
One part hydrogen to two parts oxygen?
Take away on or two parts of oxygen and bingo! No water.
Perhaps my friend you are like my wife and I.
Logic flies out of the window when the opposite sexes fight for supremacy.
But of course she cheats by turning off her hearing aid.
Oxygen saturation is a function of ambient temperature and mixing. Basically if the boiled water is allowed to cool the water will reabsorb the lost gasses including oxygen. If you increase the temperature you decrease the solubility of a gas in a liquid.The opposite is true on if you decrease the temperature......
I hope this helps from basics physics....
