How does hot and cold work?

Question

I know that when something is cold or hot it’s just our sense of when molecules move slower or faster but I don’t understand why that can kill you. Why can something damage you if its molecules just move slower or faster?

Answer 1

Because you are mostly little bags of water called cells. Heat and cold can both make those cells burst. They burst and die and because it happens fast holes open up on a larger scale. Cold also prevents most of the chemicals in your body from moving correctly.
