Which pair of properties apply to a substance in the solid state but not the liquid state?

• A. Indefinite shape and ability to flow
• B. Compressibility and indefinite volume
• C. Definite shape and fixed volume
• D. Ability to fill the container and high kinetic energy

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the difference between physical properties of solids and liquids. Solids have a definite shape and fixed volume, while liquids have a definite volume but an indefinite shape.
2. Step 2: Analyze the property 'indefinite shape and ability to flow' — this describes liquids, not solids, because solids have a definite shape and do not flow easily.
3. Step 3: Consider 'compressibility and indefinite volume' — solids and liquids are generally incompressible, and solids have a definite volume, so this does not apply to solids.
4. Step 4: Look at 'definite shape and fixed volume' — these are characteristic properties of solids, distinguishing them from liquids which have indefinite shape.
5. Step 5: Evaluate 'ability to fill the container and high kinetic energy' — this describes gases, not solids or liquids, since solids do not fill containers and have lower kinetic energy.
