Answer

For dilution of conc. H₂SO₄, the conc. acid is added to water and not the water to the acid even though heat is evolved in both cases.

If water is added to the acid : There is a sudden increase in the temperature and the acid being in bulk tends to spurt out.
If acid is added to water : The water is in bulk and the acid being heavier settles down. The heat evolved is dissipated in the water itself and hence the spurting of the acid is minimized.
