Question

Explain Endothermic reaction with example.​

Answer 1

Answer:

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such aprocess, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Melting ice cubes.

Melting solid salts.

Evaporating liquid water.

Answer 2

ANSWER

ENDOTHERMIC REACTION:-

It is a reaction in which heat is absorbed .

EXAMPLE:-

Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen.

OTHER EXAMPLES :-

• Melting of ice cubes .
• Making an anhydrous salt from a hydrate.
• Melting solid salts.
• Sublimation of dry ice into carbon dioxide gas.
