Answer;
Respiration in cells, photosynthesis, activating a cod pack- absorb energy
Producing electric current, burning a candle, baking bread- release energy
Explanation;
-The chemical reactions that absorb energy are called endothermic reactions. These reactions absorb more energy than they release. When endothermic reactions absorb energy, a temperature drop is measured during the reaction.
The chemical reactions that release energy to the surroundings are called exothermic reactions.Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy.
