Sound travels faster in ............... than in liquids.

Explanation

**Step-by-Step Solution:**

1. **Understanding Sound Transmission**: Sound is a form of energy that travels in the form of vibrations. It requires a medium to propagate, which can be solid, liquid, or gas.

2. **Comparing Different States of Matter**:
- In solids, the molecules are tightly packed together. This strong molecular bond allows vibrations to pass quickly from one molecule to another.
- In liquids, the molecules are less tightly packed than in solids, which means that the vibrations take longer to transfer.
- In gases, the molecules are far apart, making it even slower for vibrations to travel.
