Ashish was performing an experiment by setting up an arrangement as shown in the figure.

Which of the following relations holds correct regarding the amount of water that got collected in beakers 1, 2 and 3 after an hour?

A Beaker 1 > Beaker 2 > Beaker 3
B Beaker 1 > Beaker 3 > Beaker 2
C Beaker 3 > Beaker 1 > Beaker 2
D Beaker 3 > Beaker 2 > Beaker 1


The correct answer should be A because water is least absorbed by sandy soil and is absorbed the most by clayey soil.

Ans 1:

Ishti Rawat from Pawar Public School, Pune
Class : Class 5
we use clay pots because they do not absorb water so beaker 1 will have most water. while making sandcastles we put water in soli because sand absorbs water the most, thus leading to the fact that in beaker 3 least water will be there. thus, i think that the correct answer is A
