Answer 1

rigidity is the ability of a substance to maintain its shape even if high pressure is applied.
compressibility is ability of substance to decrease it's volume when extreme pressure is applied
density is the mass per unit of matter.
solids are more denser and rigid than other states and gases are more compressible than other states

Answer 2
