Answer 1

Fluids are those substance which can flow easily at room temperature
example are water , oil , glycerin , etc.


according to Archimedes principle
when an object is wholly or partially immersed in water it experience a buoyant force which is equal to the weight of the water displace by the object

if the density of the substance is higher than the liquid so it will sink
if the density is lower then it will float
