I saw one question:

Which material does not float on water?
(1) ceramic (2) wood
(3) rubber (4) plastic

I put (3) rubber.

Answer says (1) ceramic.


Can anyone answer why is this so??
Will be grateful for your advice.

Thank you

a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
