Step 2:
: Understanding Molecular Motion

Molecular motion is directly related to the temperature and kinetic energy of the molecules in a substance. The state of matter with the fastest molecular movement is determined by the molecules' ability to move freely.

Step 3:
: Comparing Molecular Movement in Different States

- Solids: Molecules are tightly packed in a fixed lattice structure - Molecules vibrate in place - Least amount of movement - Lowest kinetic energy - Liquids: Molecules have more freedom of movement - Can move past each other - More mobility than solids - Intermediate kinetic energy - Gases: Molecules have maximum freedom of movement - Molecules move rapidly and randomly - Can spread out and fill entire container - Highest kinetic energy

Step 4:
: Analyzing Molecular Kinetic Energy

- $$v$$ is velocity of the molecule
The kinetic energy of molecules is represented by the equation: Where:

Step 5:
: Conclusion

Gases have molecules that move the fastest due to: - Least intermolecular forces - Maximum freedom of movement - Highest average kinetic energy

Final Answer

Gas is the state of matter with molecules that move the fastest.
