Answer:Endothermic reactions are chemical reactions that absorb heat from their surroundings. Examples include:
Dissolving an effervescent tablet in water (releasing carbon dioxide gas)
Photosynthesis in plants
Melting of ice
Exothermic reactions are chemical reactions that release heat into their surroundings. Examples include:
Combustion of fossil fuels (e.g. gasoline, coal)
Cooking food (e.g. baking, grilling)
Rusting of iron
Respiration in humans and animals
Chemical hand warmers that release heat when activated.
