Question

Give an example each of an exothermic and an endothermic process .​

Answer 1

Explanation:

Enfothermic and Exothermic reactions are those which absorbs or releases heat respectively.

Some of the examples of Exothermic reactions are as;

1. Making ice cubes
2. Formation of Snow in cloud
3. Condensation of rain from water vapour
4. A Candle flame
5. Crystallization of Liquid salt.

Examples of Endothermic reactions are given as ;

1. Melting of ice cubes
2. Conversion of frost to water vapour
3. Evaporation of water
4. Forming a cation from an atom in the gas phase
5. Melting solid state.

Answer 2

Answer:

Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction. The categorization of a reaction as endo- or exothermic depends on the net heat transfer.
