Understanding States of Matter
Matter exists in different states, primarily solid, liquid, gas, and plasma. Each state has unique characteristics based on the arrangement and behavior of its particles.
Characteristics of Solids
- Definite Shape: Solids maintain a fixed shape. This means that if you have a block of wood or a metal cube, they will not change shape unless physically altered.
- Definite Volume: Solids occupy a specific amount of space. No matter how you place a solid object, it will always take up the same volume.
Comparison with Other States
- Liquids:
- They have a definite volume but no definite shape. Liquids take the shape of their container, like water in a cup.
- Gases:
- Gases have neither a definite shape nor a definite volume. They expand to fill the entire space available, like air in a balloon.
- Plasma:
- Plasma, like gas, does not have a definite shape or volume. It consists of charged particles and is found in stars, including the sun.
Conclusion
The correct answer is option 'C' because solids are the only state of matter that possesses both a definite shape and volume, making them distinct from liquids, gases, and plasma. Understanding these differences is crucial for grasping the fundamental properties of matter.
