उत्तर
LIQUID PRESSURE DEPENDS ON THE ’DENSITY OF LIQUID: Take two identical balloons attached to one end of each of two identical glass tubes opened at both ends.
Fill tube (a) with milk and tube (b) with alcohol to the same height.
We notice that balloon attached to the tube (a) bulged more than balloon attached to the tube (b). This shows that the same height of milk exerts more pressure than alcohol. Since the density of milk (1.03) is more than density alcohol (0.8).
