Question

. Which
pairs of processes involves absorption of heat from the surroundings? *

Answer 1

• An endothermic process is any process which requires or absorbs 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.

Answer 2

Answer:

endothermic

Any process that absorbs heat from its surroundings is an endothermic process. Therefore, all endothermic reactions are endothermic processes. However, the opposite is not true. Many endothermic processes involve physical changes rather than chemical changes.
