Question

MILY TO
Take coin, dry leaf, saw dust, cork and put them in water. Try to find out which one will sink
and which one will float. Write your observation on A4 size sheet and write the possible reason
for floating and sinking of objects ​

Answer 1

Answer:

All those items that have more density than water would sink and those items that have less density would float.

Explanation:

Coin, made up of metal, is obviously more dense than water and would sink in the water immediately.

While cork is less dense and also has entrained air will float on the water.

Similarly, the sawdust and dry leaves would also float on the water since they contain entrained air and also less dense than water.
