While diluting an acid, why is it recommended that the acid should be added to water and not water to the acid?

Explanation

A concentrated acid is diluted by adding water of it. The process of mixing water to a concentrated acidis highly exothermic in which a large amount of heat is evolved.
(i) When the concentrated acid is added to water, then the heat is evolved gradually and easily absorbed by the large amount of water.
(ii) If water is added to concentrated acid, then a large amount of heat is evolved at once. This heat changes some of the water to steam explosively which can splash the acid on our face or clothes and cause acid burns.
