Particles of matter in gaseous state have more kinetic energy than in solids.

Answer

**Step-by-Step Solution:**

1. **Understanding Kinetic Energy:**
- Kinetic energy is the energy that an object possesses due to its motion. The more an object moves, the more kinetic energy it has.

2. **Comparing States of Matter:**
- Matter exists in three primary states: solid, liquid, and gas. Each state has different characteristics regarding the arrangement and movement of its particles.

3. **Particle Movement in Solids:**
- In solids, particles are tightly packed together and have very limited movement. They can only vibrate in place, which means they have low kinetic energy.

4. **Particle Movement in Gases:**
- In gases, particles are much farther apart compared to solids. They move freely and randomly, colliding with each other and the walls of their container. This random and fast movement indicates that gas particles have high kinetic energy.

5. **Conclusion:**
- Since gas particles are able to move more freely and rapidly due to the large spaces between them, they possess more kinetic energy than particles in a solid state. Therefore, the statement "Particles of matter in gaseous state have more kinetic energy than in solids" is **true**.
