State whether the statement is true or false. No gas is ideal gas, all gases are real gases.

Answer

To determine whether the statement "No gas is ideal gas, all gases are real gases" is true or false, we can analyze the concepts of ideal gases and real gases.

### Step-by-Step Solution:

1. **Understanding Ideal Gases**:
- Ideal gases are defined by the kinetic theory of gases, which assumes that gas molecules have negligible intermolecular forces and occupy no volume. This is a theoretical concept used to simplify the behavior of gases under certain conditions.

2. **Characteristics of Ideal Gases**:
- In ideal gas behavior, the gas molecules are assumed to move randomly and collide elastically. The interactions between the molecules are considered negligible, meaning they do not affect the gas's behavior significantly.

3. **Real Gases**:
- Real gases, on the other hand, do exist in nature and exhibit behaviors that deviate from the ideal gas law, especially under high pressure and low temperature. Real gases have intermolecular forces and occupy space, which affects their behavior.

4. **Conclusion**:
- Since ideal gases are a hypothetical concept and do not exist in reality, we can conclude that no gas is an ideal gas. Therefore, it is accurate to state that all gases are real gases.

5. **Final Statement**:
- The statement "No gas is ideal gas, all gases are real gases" is true.
