Gas to solid

Answer 1

Here's the completed chart for the phase changes regarding kinetic and potential energy:

| State of matter | Kinetic Energy | Potential Energy |
|-------------------|----------------|------------------|
| Liquid to gas | increase | increase |
| Liquid to solid | decrease | increase |
| Solid to liquid | increase | decrease |
| Solid to gas | increase | increase |
| Gas to liquid | decrease | decrease |
| Gas to solid | decrease | increase |

### Explanation:
- **Liquid to gas**: Both kinetic and potential energy increase as molecules move more freely in gas.
- **Liquid to solid**: Kinetic energy decreases (molecules move less), potential energy increases (molecules are held in a more structured arrangement).
- **Solid to liquid**: Kinetic energy increases (molecules move more freely), potential energy decreases (molecules are less structured).
- **Solid to gas**: Kinetic energy increases (molecules move significantly faster), potential energy increases (molecules are further apart).
- **Gas to liquid**: Kinetic energy decreases (molecules move less), potential energy decreases (molecules are brought closer together).
- **Gas to solid**: Kinetic energy decreases (molecules move much less), potential energy increases (molecules arrange into a more structured state).
