Why are burns due to chemicals or intense cold also called “burns”? What do they have in common with the regular burns due to fire or heat?

Question

Not sure whether to flair this as biology or physics, but any idea why?

Answer 1

i burned myself with something that was frozen quite hard by boiling liquid helium last week (so probably double digit kelvin, max 100 maybe). Fortunately enough I was quick to remove my arm. It stayed painfull for a few days and felt exactly like a “hot” burn.

Now my skin feels weird and heals slowly.

Stay away from cryogenic stuff kids.
