1The endothermic reaction in the experiment caused the mixture to cool down significantly.
2Is the process of photosynthesis in plants an endothermic or exothermic reaction?
3The researchers found that the endothermic decomposition of the compound required careful control of temperature and pressure.
4Try to identify which step in the manufacturing process is endothermic and requires additional energy input.
5The endothermic nature of the reaction explains why it is often necessary to heat the reactants to initiate the process.
