Why do solids have a definite shape and volume?
Understand the Problem
The question is asking for an explanation of the properties of solids, specifically why they maintain a definite shape and volume. This involves understanding the molecular structure and interactions within solid materials.
Answer
Molecules in solids are fixed in position and closely packed, providing a definite shape and volume.
Solids have a definite shape and volume because their molecules are fixed in position and closely packed together.
Answer for screen readers
Solids have a definite shape and volume because their molecules are fixed in position and closely packed together.
More Information
The fixed and closely packed molecules in solids result in strong intermolecular forces, which give solids their rigidity and resistance to shape change.
Tips
A common mistake is to think that molecules in solids do not move at all. They can vibrate in place, but do not move from one part of the solid to another.
