Endothermic VS Exothermic Reactions

Study Notes

Endothermic Reactions

Involves heat absorption, making heat a reactant in the process.
Examples include boiling water, where heat enters to facilitate boiling.
Evaporation is another endothermic process, taking in heat to transform water into steam.
Baking a cake requires heat to enter for the cake to rise and cook.
Cooking an egg also involves heat absorption for proper cooking.
Photosynthesis is an endothermic reaction where plants absorb heat from sunlight to produce energy.
Dry ice creates fog by absorbing heat from the surrounding environment.

Exothermic Reactions

Involve heat release, categorizing heat as a product of the process.
Freezing water into ice cubes illustrates this as heat leaves the water, resulting in ice formation.
Boiling water is the opposite of freezing in terms of heat transfer, as boiling is endothermic.
Condensation forms on cold drinks when heat leaves the water, turning it into droplets.
Burning a candle exemplifies an exothermic reaction, where heat is expelled from the flame.
Lighting a match releases heat from the burning process.
Air-activated hand warmers give off heat to warm the hands, making it an exothermic reaction.
The reaction of magnesium with oxygen releases heat, classifying it as exothermic.
