Question

In ENDOTHERMIC reactions, energy is _____ by the reaction system from the surroundings.

  1. Absorbed
  2. Released
  3. Eliminated
  4. Obliterated

hintHint:

Endothermic reactions are those chemical reactions in which the reactants absorb heat energy from the surroundings to form the products. 

The correct answer is: Absorbed


    In ENDOTHERMIC reactions, energy is absorbed by the reaction system from the surroundings.
    • Chemical processes referred to as endothermic reactions occur when the reactants take in heat energy from their environment to yield products.
    • These reactions produce a cooling effect by bringing the temperature of the space around them down.
    • Ice cubes absorb heat energy from their surroundings and melt to generate liquid water as an example of an endothermic physical process (no chemical bonds are broken or formed).
