According to kinetic theory of gases, which one of the following statement (s) is/are not true?

Options

A. Real gas behave as ideal gas at high temperature and low pressure
B. Liquid state of ideal gas is impossible
C. At any temperature and pressure, ideal gas obeys Boyle's law and Charles' law
D. The molecules of a real gas do not exert any force on one another

Explanation

To determine which statement(s) about the kinetic theory of gases is/are not true, we will analyze each statement based on the principles of the kinetic theory.

### Step-by-Step Solution:

1. **Understanding the Kinetic Theory of Gases**:
- The kinetic theory of gases describes the behavior of ideal gases and provides insights into the properties of real gases. It assumes that gas molecules are in constant random motion and that they collide elastically with each other and with the walls of their container.

2. **Analyzing Each Statement**:
- **Statement A**: "Real gases behave like ideal gases at high temperature and low pressure."
- This statement is true. At high temperatures and low pressures, the intermolecular forces become negligible, and real gases tend to behave similarly to ideal gases.

- **Statement B**: "Liquid state of ideal gas is impossible."
- This statement is also true. Ideal gases do not condense into a liquid state under any conditions because they are defined as having no intermolecular forces.

- **Statement C**: "At any temperature and pressure, ideal gas always boils slow and charges slow."
- This statement is true. Ideal gases do not undergo phase changes like real gases do, and they do not exhibit boiling or condensation in the same manner as real gases.

- **Statement D**: "The molecules of real gases do not exert any force on one another."
- This statement is false. Real gas molecules do exert forces on one another due to intermolecular attractions and repulsions. The pressure exerted by a gas is a result of the collisions of gas molecules with the walls of the container, which is a direct consequence of these forces.

3. **Conclusion**:
- The only statement that is not true according to the kinetic theory of gases is Statement D.

### Final Answer:
The statement that is not true is **D**: "The molecules of real gases do not exert any force on one another."
