What you can learn
- In a solid, particles vibrate in fixed positions.
- In a liquid, particles slide past each other but stay close.
- In a gas, particles have enough energy to escape each other's attraction and fill the container.
Frequently asked questions
What happens to particles when a solid melts?
They gain enough kinetic energy to break out of their fixed positions, though they stay close together as a liquid.
Why does temperature stay flat during a phase change?
The added energy goes into breaking attractions between particles instead of making them move faster, so the temperature holds steady until the change is complete.
