Question

give 5 examples of exothermic and endothermic reactions from daily life​

Answer 1

EXOTHERMIC REACTION

• Condensation of rain from water vapor.

• Cement and concrete setting.

• Combustion of fuels.

• Epoxy raisin setting.

• Mixing of water and acid.

ENDOTHERMIC REACTION

• Melting ice cubes
• Melting solid salts
• Evaporating liquid water
• Converting frost to water vapor
• Cooking an egg

Answer 2

Examples of Exothermic Reactions in daily life:

1. Respiration: Respiration is responsible for the normal functioning of the body and occurs in each cell.
2. Ice cubes: For the formation of water into ice cubes, latent heat is expelled out.
3. Hot bags: We use hot bags in case of an injury in order to supply heat. The hot bags have either gel or water that releases heat and provides warmth.
4. Rusting of iron: Rusting is a natural phenomenon that results in release of heat.
5. Match stick: While lighting a matchstick along with fire, heat is given out.

Examples of Endothermic Reactions in daily life:

1. Melting ice cubes
2. Evaporation of water from ponds, lakes, etc
3. Ice packs that cool sweeling or injury
4. Baking bread in oven
5. Photosynthesis
