Solid Properties Explained

This question asks to identify the true properties of solids from the given options.

Analyzing Solid Characteristics

Let's examine each characteristic:

• a. Definite shape: Solids maintain a fixed shape, regardless of the container they are in. Their particles are held in fixed positions.
• b. Rigidity fixed: Solids are rigid materials, meaning they resist deformation. Their particles are tightly packed and vibrate in fixed positions.
• c. Volume: Solids occupy a specific, fixed amount of space.

All three properties listed (definite shape, fixed rigidity, and definite volume) are fundamental characteristics of the solid state of matter.

Conclusion on Solid Properties

Therefore, statements a, b, and c are all true for solids.
