Answer:

Endothermic Chemical Reactions

A good example of an endothermic reaction includes dissolving a salt. It doesn't have to be table salt, nor does the solvent need to be water.

The reaction of barium hydroxide octahydrate crystals with dry ammonium chloride

Dissolving ammonium chloride in water

The reaction of thionyl chloride (SOCl2) with cobalt(II) sulfate heptahydrate

Mixing water and ammonium nitrate

Mixing water with potassium chloride

Reacting ethanoic acid with sodium carbonate

Photosynthesis (chlorophyll is used to react carbon dioxide plus water plus energy to make glucose and oxygen)

Endothermic Processes

These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes:

Melting ice cubes

Melting solid salts

Evaporating liquid water

Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes

Making an anhydrous salt from a hydrate

Forming a cation from an atom in the gas phase

Splitting a gas molecule

Separating ion pairs

Cooking an egg

Baking bread
