### Question: Understanding the Kinetic Molecular Theory of Gases

**Which of the following statements regarding the kinetic molecular theory of gases is NOT correct?**

1. **Gas particles are in constant, rapid, random motion.**
2. **Energy is not lost as gas particles collide with each other and container walls.**
3. **At a given temperature, the gas particles have the same velocity.**
4. **The gas particles themselves are assumed to occupy negligible volume.**

### Explanation:

The kinetic molecular theory of gases explains the behavior of gases in terms of the motion of their particles. Here is a brief explanation of each statement based on the theory:

1. **Constant, Rapid, Random Motion:** This statement is correct. According to the kinetic molecular theory, gas particles are always moving rapidly in random directions.

2. **No Energy Loss During Collisions:** This statement is also correct. When gas particles collide with each other or with the walls of the container, these collisions are elastic. No kinetic energy is lost in an elastic collision.

3. **Same Velocity at a Given Temperature:** This statement is incorrect. At a given temperature, gas particles have a range of velocities. While the average kinetic energy of the particles is the same at a certain temperature, individual particles will have different velocities due to their random motion.

4. **Negligible Volume:** This statement is correct. The volume occupied by the gas particles themselves is so small compared to the volume of the container that it is considered negligible.

In summary, **statement 3 is NOT correct** according to the kinetic molecular theory of gases.
