Question

What do you mean by exothermic and endothermic reaction? Give examples
Write the unit of humidity? Mention the maximum and minimum range of
humidity.​

Answer 1

Answer:

In exothermic reaction, heat is evolved during the reaction which is indicated by '+heat' sign on the right hand side of the equation.

In endo thermic reaction heat is absorbed which is indicated by putting '+heat'sign on the left hand side of the equation.

Answer 2

It measures the weight of water vapor per unit weight of air and it is expressed as grams of water vapor per kilogram of air g.kg-1 is the specific humidity unit.

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.
