With regard to the gaseous state of matter which of the following statement are correct ?

Options

A. Complete order of molecules
B. Complete disorder of molecules
C. Random motion of molecules
D. Fixed position of molecules

Explanation

To determine which statements regarding the gaseous state of matter are correct, we will analyze each statement based on the properties of gases.

### Step-by-Step Solution:

1. **Understanding the Gaseous State**:
- Gases are characterized by the high energy and random motion of their molecules. Unlike solids and liquids, gas molecules are not closely packed and can move freely.

2. **Analyzing the Statements**:
- **Statement A: Complete order of molecules**:
- This statement is incorrect. In the gaseous state, molecules do not have a fixed arrangement; they are in constant motion and do not exhibit order.

- **Statement B: Complete disorder of molecules**:
- This statement is correct. The molecules in a gas are in a state of complete disorder due to their high kinetic energy and random motion.

- **Statement C: Random motion of molecules**:
- This statement is also correct. Gas molecules move randomly in all directions, which is a defining characteristic of the gaseous state.

- **Statement D: Fixed position of molecules**:
- This statement is incorrect. Fixed positions of molecules are characteristic of solids, not gases. In gases, molecules do not have fixed positions and can move freely.

3. **Conclusion**:
- The correct statements regarding the gaseous state of matter are:
- **B: Complete disorder of molecules** (Correct)
- **C: Random motion of molecules** (Correct)

### Final Answer:
- The correct statements are:
- **B: Complete disorder of molecules**
- **C: Random motion of molecules**
