Are all exothermic reactions chemical changes?

Click For Summary
SUMMARY

Exothermic reactions are processes that release heat, but not all exothermic reactions qualify as chemical changes. The discussion highlights two specific examples: nuclear fission and condensation. These processes release energy without involving a chemical transformation of the substances involved. Understanding the distinction between exothermic reactions and chemical changes is crucial for accurate scientific reporting.

PREREQUISITES
  • Basic understanding of thermodynamics
  • Knowledge of chemical and physical changes
  • Familiarity with nuclear chemistry concepts
  • Understanding of phase transitions in matter
NEXT STEPS
  • Research the principles of nuclear fission and its energy release mechanisms
  • Study the thermodynamics of phase changes, particularly condensation
  • Explore the differences between chemical and physical changes in detail
  • Investigate other examples of exothermic reactions that are not chemical changes
USEFUL FOR

Students in chemistry, physicists, and educators looking to clarify the concepts of exothermic reactions and their classifications.

Are all exothermic reactions chemical changes since they release heat?:confused:
 
Physics news on Phys.org
2 changes that are exothermic yet not chemical in nature:

Fission, condensation...
