Dearest Peeps who know oh so much !


I heard that when you add a fizzy drink to ice, the drink actually gets colder than the ice is  !!  What is it with this evil sorcery !!!!!


Why's that then ?....Could we continually add more and more till we reach absolute zero ?


so:


Why when adding a fizzy drink to ice does the temperature drop below the temperature of the ice ?

I heard that

Have you checked to see whether it does?

I can see why the evaporation of CO2 will reduce the temperature, with or without the ice.

Yes.
much the same way that adding salt to ice makes it cooler.
But it won't be a big effect.
