Consider the following statements.
Thermal energy tends to keep the soild molecules apart.
Intermolecular force tends to keep the solid molecules closer.
Which of the above statements(s) is/are false?

Options

A. Only I
B. Only II
C. Both I and II
D. Neither I nor II

Answer

To determine which of the statements is false, let's analyze each statement step by step.

### Step 1: Analyze the first statement
**Statement 1:** "Thermal energy tends to keep the solid molecules apart."

- **Explanation:** Thermal energy is related to the kinetic energy of the molecules. In solids, molecules are closely packed, but as the temperature increases, the thermal energy increases, causing the molecules to vibrate more vigorously. This increased motion can lead to the molecules moving slightly apart from each other. Therefore, this statement is **true**.

### Step 2: Analyze the second statement
**Statement 2:** "Intermolecular force tends to keep the solid molecules closer."

- **Explanation:** Intermolecular forces are the attractive forces between molecules. In solids, these forces are strong enough to hold the molecules tightly together, preventing them from moving freely. This means that intermolecular forces indeed act to keep the solid molecules close to each other. Therefore, this statement is also **true**.

### Conclusion
Since both statements are true, we can conclude that there are no false statements among the options provided.

### Final Answer:
Neither statement 1 nor statement 2 is false.
