Question

The solids cannot be compressed because:

• A. the inter particle attraction forces are very weak
• B. the movement of the constituent particles are not restricted
• C. the constituent particles are closely packed
• D. none of the above

Answer 1

Answer: (C)

the constituent particles are closely packed

Solids are held in fixed positions, they can only vibrate. Because the particles can not move, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.
