Explain the following terms with
exgmples.
4. Endothermic reaction:-An endothermic process is any process which requires or absorbs thermal energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
E.g.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 vapour (melting, boiling, and evaporation, in general, are endothermic processes.
