0 taking place or being formed by absorbing heat:
In an endothermic reaction, the temperature of the surroundings decreases.
Melting, evaporation and boiling are endothermic processes.
Is the overall reaction exothermic or endothermic?
Chemical reactions which absorb energy from the surroundings are described as endothermic.
This gives a mixture of carbon monoxide and hydrogen in an endothermic reaction.
The decomposition of hydrogen iodide is an endothermic reaction.
Bond breaking is endothermic and bond forming is exothermic.
