Thread: Co2

While we drink or eat some hot thing. We usually puff or breathe out air to cool the substance. My friend says in doing so we exhibit Co2 gas in the matter which spoils our food. Is it really so?
Thanks

When we blow on food you have to remember it is not just Co2, it has small amounts of oxygen, nitrogen and other gases. Also it is not exactly highly concentrated on our food. So I think that it does not spoil our food at all. Oh and does your friend ever drink coke with food? Because if so doesn’t that have a lot more carbon dioxide in it than our breathe?

I truly accept your view indeed..

define spoiled... i mean if by spoiled u mean saturated with CO2 then possibly but i mean i'm eating tomato soup right now and blowing on it to cool it down, and the taste has not changed nor is there any visible spoiled spots in it.

More likely CO2 preserves it, after all oxygen seems to be the element that provides the mechanism for things to go 'rotten'.

plus i dont really think you can just blow on something and automatically add CO2 to it.

if the food came from a plant, that plant produced the food while processing CO2. maybe your adding quality...

Ah! so that's where all the gas comes from eh?

Also ... the CO2 can combine with water to make carbonic acid .... which would have a pH to kill bacteria : /

Your friend had some bad information

Looks like a clean cut case of "Myth busted!"

... Next!

also, if we blow repeatetly (wow this is sounding weirder by the minute: all you high schoolers probobly know what im talking about ) then your body gets less and less of a chance use up the oxygen and replace it with CO2 since you are only holding the air in your lungs for a second.

you can be 70 and still understand that one!

Thanks now I have enough stuff to explain my friend about it.
I was thinking of the same as your answers were but was ascertain about it.
Thanks.

is this why some people drink coke or carbonitedwater while having a stomach ache?
How good is coke for you, while you have a stomach ache (if it is a virus or bacteria)

lol? i think bacteria which can survive in stomach acid, would be able to handle a bit of coke... :P
