If water ice is removed from a freezer where temp is minus 100 deg. F, will it keep drinks colder longer?

Question

I'm not dumb, but feel a little dumb asking this. I'm assuming that the ice will also have a temp of minus 100 degrees F, even though it froze at 32 deg. F, but would it really keep drinks colder longer in the glass? If you got water ice as cold as dry ice would it work just as well keeping things cold????

Answer 1

Yes it would. The ice would not start melting until it reached the freezing point.

annumous...ice does NOT stay at 32 deg. It only stays at 32 during the phase transition from liquid to solid. After it solidifies, ice can continue to cool like any other solid.

The purpose of adding salt to the ice in an ice cream maker is to lower the freezing point of the ice-water solution. That solution is at phase transition so the salt does have a slight effect in depressing the transition temperature.

Answer 2

Yes, you are right. The ice at -100 F would be colder than at 32. It would really hard to get the ice that cold, but in theory it would work.

Answer 3

no it wouldnt. ice stays at 32. thats why u need rock salt in ice to make home made ice cream.it lowers the frexing point. allwing the ice to get colder then 32 only the verry outter eage would be colder. the core would stay at 32
