Question
When you heat a sample of a solid, the particles in it become:
- Bigger
- Low mass
- faster
- Slow
Hint:
When a solid is heated particles gain energy.
The correct answer is: faster
- When a solid is heated the particles gain energy and start to vibrate faster and faster.
- Initially, its size becomes bigger and the forces of attraction are weakened further weakening the structure.
- As the structure is weakened it affects the expansion of the solid.
- After a certain point, it reaches a stage when they overcome the forces of attraction and move away from each other.
- Finally, this results in the melting of the solid.

What is meant by dry ice?
- It's called "dry ice" because it does not melt like wet ice.
- Instead, dry ice converts into carbon dioxide gas (sublimation).
