When a chemical cold pack is activated, a chemical reaction occurs that causes the pack to feel cold.

- Describe the transfer of energy betwen a cold pack and the air around it.

  • Chemistry -

    The cold pack gets colder; the air around it gets warmer.

  • Chemistry -

    The cold pack gets colder the air around it gets warmer

  • Chemistry -

    The reaction is endothermic. Endothermic reactions always feel cold, and heat is being absorbed by the back from the surrounding environment.
