Why Is Evaporation Endothermic - Lisbd-Net. Com
Phase Transition Direction of Δh Sublimation (Solid to Gas) Δh>0; Enthalpy Increases (Endothermic Process) Freezing (Liquid to Solid) Δh
| Phase Transition | Direction of ΔH |
|---|---|
| Sublimation (solid to gas) | ΔH>0; enthalpy increases (endothermic process) |
| Freezing (liquid to solid) | ΔH<0; enthalpy decreases (exothermic process) |
| Condensation (gas to liquid) | ΔH<0; enthalpy decreases (exothermic process) |
Why is photosynthesis considered an endothermic reaction?
Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
What does one mean by exothermic and endothermic reactions explain and support your answer with one chemical equation for both?
A chemical reaction in which a large amount of heat / energy is produced along with the products is called exothermic reaction. A chemical reaction in which a large amount of heat / energy is absorbed is called endothermic reaction.
