Question

s Activity–2 : To show that liquid pressure depends only upon the height of the liquid column and not the volume of the liquid.
Material required -Three to four transparent plastic bottles of different capacities (2 litre, 1.5 litre, 1 litre and 0.5 litre), Nail or compass to make holes in the bottle, Cello tape, Meter scale, Paper cup, a wooden stool or table to be used as a stand, water.
Method-
 Take three transparent plastic bottles of different capacities.
 Make one hole on the side of each of the bottle at the same distance from the base of the bottles.
 Seal these holes with cello tape
 Make a mark near the top of the bottle of least height .Measure the height of this
mark from the bottom. Make marks at this height in the remaining two bottles too.
 Fill each bottle with water using a paper cup. Note that the level of water is the same in all the bottles (till the mark made on each bottle). Count the number of cups used to fill each of the bottles.

 Place one of the bottles on the wooden stool or table. Remove the
cello tape from the hole. The water stream will come out of the hole.
 Mark the point at which the water stream falls on the floor.
 Measure the distance of this mark from the base of the stand.
