What is the characteristic of a solid substance?

• A. It takes the shape of its container
• B. Its molecules are spread out
• C. Its molecules are tightly packed and maintain their shape
• D. It flows freely

Answer: (C)

The characteristic of a solid substance is that its molecules are tightly packed and maintain their shape. In solids, the particles are closely packed together in a fixed arrangement, which prevents them from moving freely. This structure gives solids their definite shape and volume. Unlike liquids and gases, where particles are more spaced out or can move freely, solids retain their shape regardless of the container they are in. This is fundamental to understanding the physical properties of matter and helps distinguish solids from other states of matter.
