Energy changes accompanying the chemical reactions can take place

How the chemical reaction takes place?

With the help of an activity, show that there is no change in mass when a chemical change (chemical reaction) take place.

What are the conditions required for a chemical reaction to take place?

Evaporation of water is: a process in which heat is neither evolved nor absorbed a process accompanied by chemical reaction an exothermic change an endothermic change.
