Re: Putting Coke in Freezer to cool faster?
It definitely cools faster in the freezer.
However, the thermal conductivity of air is very small. I'm not sure if this was the reason that your friend was thinking that it wouldn't be faster. It still will be, but there's an even faster way.
The thermal conductivity of solids/liquids is much greater. This is why putting the soda into a cold water bath with ice (i.e. in a cooler) will chill it much much faster than fridge or freezer.
