Answer

To analyze the statements provided in the question, we will evaluate each statement and determine their validity based on principles of physics, particularly in the context of thermal expansion and intermolecular forces.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- Statement 1 claims that "Liquids usually expand more than solids."
- This is generally true. When heated, liquids tend to expand more than solids because the particles in liquids are less tightly packed compared to those in solids. Therefore, when temperature increases, the kinetic energy of liquid particles increases, leading to a greater expansion.

**Hint**: Consider how particle arrangement and movement differ in solids and liquids when heated.

2. **Understanding Statement 2**:
- Statement 2 states that "The intermolecular forces in liquids are weaker than in solids."
- This statement is also true. In solids, particles are held together by strong intermolecular forces, which keep them in fixed positions. In contrast, the intermolecular forces in liquids are weaker, allowing particles to move more freely and thus expand more easily when heated.

**Hint**: Reflect on how the strength of intermolecular forces affects the state of matter and their response to temperature changes.

3. **Connecting the Statements**:
- Statement 2 provides a correct explanation for Statement 1. The weaker intermolecular forces in liquids allow them to expand more than solids when subjected to the same increase in temperature.
- Therefore, both statements are true, and Statement 2 correctly explains why Statement 1 is true.

**Hint**: Think about how the properties of materials relate to their molecular structure and behavior under thermal conditions.

4. **Conclusion**:
- Since both statements are true and Statement 2 explains Statement 1, we conclude that the relationship between the two statements is valid.

**Final Answer**: Both statements are true, and Statement 2 is the correct explanation for Statement 1.
