Which of the following statements is true? A. Shape: Depending on the type of substance, shape varies based on the position of particles. For example, solids have a definite shape whereas liquids take the shape of their container and gases have no shape. B. Compressibility: It is a property of a substance that flows easily and allows a change in its shape under external forces, and this property is exhibited by both liquids and gases.
Only A is true.
Only A is true. is correct.
Statement A correctly describes the shape property of matter: solids have a fixed shape because their particles vibrate in fixed positions, liquids adopt the shape of their container because particles can slide past one another, and gases have no fixed shape at all.
Statement B defines compressibility incorrectly. The description given — the ability to flow easily and change shape under external force — is actually the definition of fluidity, which is shared by liquids and gases. Compressibility, strictly, is the property of being squeezable into a smaller volume, and among the three states it is prominently shown by gases (liquids and solids are only very slightly compressible). Since B labels the wrong property with the name 'compressibility', only A is a true statement.
