Are N2O and CO2 chargers interchangeable for culinary purposes?
Cream whippers seem to use N2O chargers.
Soda siphons seem to use CO2 chargers.
But both chargers appear to be physically identical. The MyPressi espresso device, which uses chargers to force water through a coffee puck at 9 bar like a benchtop machine is apparently happy to use either.
So can cream whippers use CO2, and soda N2O?
For example:
- Is 'nitrogenated' water as safe as carbonated?
- Might one cool more than the other? (cooling being preferable for whipping cream but bad for maintaining espresso water temperature)
- Assuming both contain the same liquid volume, would one or the other give greater gas expansion and more usable output?

N2O is more stable than CO2. Mixing N2O with water or cream won't create diffetent molecules. If the liquid you add N2O is not very thick (as water) the gas and liquid will separate in two. If it is thick, as with cream, the gas will get trapped in it. You can see the proccess with more detail in this question.
CO2 reacts with water (H2O) making H2CO3 (carbonic acid). It makes soda water, which has a slight acid taste, and get bubbles of released CO2 if the pressure of the soda water falls. CO2 can be used for whipping cream, but it will give acid taste to it. You can get some more information from the Wikipedia entry.
None of them cools liquids. The chargers get cooled down when opened, as the gas inside them decreases pressure. But that gas goes to the cream whipper or the soda siphon, which theoretically should increase its temperature, but having a much larger volume than the charger makes that increase unnoticeable.
When using pressure gas to make espresso, you arent pouring that gas to a closed recipient: the water escapes thru the coffee puck, so it won't cool the water. MyPressi V1 put the gas in the middle of the water chamber, so it could only be used with N2O. V2 of the device puts the gas in the top part of the chamber, so it is not mixed with the water, making it suitable to be used with CO2.

Can you use CO2 cartridges for whipped cream?
N20 ( Nitrous Oxide) is the only gas that can be used in your whipped cream dispenser to make whipped cream. You CANNOT use C02, to make whipped cream in your dispenser, I'll say it again, you can absolutely positively not use Co2 to make whipped cream with your whipped cream dispenser.Are soda and cream chargers the same?
The real difference is the actual gas that you are using \u2013 a soda syphon cartridge is a pressurized canister of carbon dioxide (CO2) whereas a cream charger is a canister of Nitrous Oxide (N2O). It is the different properties of these two gasses that give them entirely different culinary purposes.Is CO2 and N2O the same?

Some chargers are compatible with all cream dispensers while others only fit onto the ones from the same brand. So, make sure that the charger you're opting for is compatible with the cream maker that you own.How to Make Nitro Espresso Old Fashioned

Answer 2
Nitrogen and probably N2O don't dissolve well in water so that wont work. CO2 dissolves well + forms a weak acid that converts back to CO2 as the CO2 is released from the water. That is why almost all bubbly drinks use CO2. There are some other gasses that would work (aka non toxic and dissolve well but they are too expensive.
So N2O soda no... or not really, you might get some bubbles but not that slightly acidic taste carbonated drinks have.
CO2 cream probably also wont work since the CO2 will dissolve in the water that is in the cream and make it go bad. It might be ok if you eat it as soon as you make it but I doubt it. N2O on the other hand does not dissolve but fluffs out the cream same as whipping it does (except that introduces nitrogen and oxygen and trace amounts of other gasses.
N2O soda would be safe, although probably not fun since you need to breath the N20 for fun.
