Why does dry ice burn??

Question

Why does dry ice burn??

Answer 1

Of course , it's cold.

Answer 2

The skin contains different sensors for cold and heat,

The sensors discriminate between cold and heat only within certain bounds. Touching dry ice overwhelms the discriminatory sensors and triggers pain. Freezing is a paramount threat to the body. You feel the pain as a burning sensation.

Answer 3

It doesn't.  It freezes because it is really cold (-70 C or something like that, I used to know).  It is just that the pain of extreme cold is the same as the pain of extreme burn and your mind doesn't know the difference.
