To which physical state of matter do the following statements apply?
$(i)$ Incompressible,no fixed shape
$(ii)$ Incompressible,high melting point
$(iii)$ Compressible,no definite volume
$(iv)$ Incompressible,highly fluid

(A) $(i)$ Liquid: Liquids are incompressible and take the shape of the container,meaning they have no fixed shape.
$(ii)$ Solid: Solids are incompressible and generally have high melting points due to strong intermolecular forces.
$(iii)$ Gas: Gases are highly compressible and do not have a definite volume or shape.
$(iv)$ Liquid: Liquids are incompressible and exhibit high fluidity,allowing them to flow easily.
