How are exothermic and endothermic connected?

Answer 1

Exothermic and endothermic processes are connected through the transfer of energy during chemical reactions. Exothermic reactions release energy, usually in the form of heat, to the surroundings, resulting in an increase in temperature. Conversely, endothermic reactions absorb energy from the surroundings, leading to a decrease in temperature. Together, they illustrate the conservation of energy in chemical processes, as the energy released in exothermic reactions can be utilized in endothermic reactions.
