  • As heat is absorbed the temperature drops?

    Kind of confusing.

  • @grayshorts Because heat or energy is converted into something else in the chemical reaction, and surrounding heat will flow into the place of reaction (now very cold) in order to reach thermal equilibrium (usually from higher temperature to lower). That's why when heat is absorbed the temperature drops.
