The main difference between Endothermic and Exothermic: Endothermic reactions absorb heat while exothermic reactions release heat. Understanding both is crucial for CBSE chemistry and physics.
Endothermic vs Exothermic — Comparison Table
| Basis | Endothermic | Exothermic |
|---|---|---|
| Heat transfer | Absorbs heat from surroundings | Releases heat to surroundings |
| Temperature change | Surroundings get cooler | Surroundings get hotter |
| Delta H | Positive enthalpy change | Negative enthalpy change |
| Examples | Melting ice, photosynthesis | Burning, respiration |
| Products energy | Products have higher energy | Products have lower energy |
Key Points
- Endothermic requires energy input to proceed
- Exothermic releases energy spontaneously
- Most combustion reactions are exothermic
- Melting ice is endothermic while freezing is exothermic
