Which of the following statements are correct ?

Options

A. It is not possible to compress a gas at a temperature below `T_(C)`
B. At a temperature below `T_(C)` the molecules ar close enough for the attractive forces to act, and condensation occurs
C. No condensation takes place above `T_(C)`
D. Due to higher kinetic energy of the gas molecules above `T_(C)`, it is considered as super critical fluid

Explanation

To determine which statements are correct regarding the behavior of gases, particularly in relation to the critical temperature (Tc), we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Critical Temperature (Tc)**:
- The critical temperature (Tc) is the temperature above which a gas cannot be liquefied, regardless of the pressure applied. Below this temperature, gases can be compressed into liquids.

2. **Analyzing Statement 1**:
- Statement: "It is not possible to compress a gas at a temperature below Tc."
- Analysis: This statement is incorrect. It is indeed possible to compress a gas at temperatures below Tc. In fact, gases can be liquefied when compressed below their critical temperature.

3. **Analyzing Statement 2**:
- Statement: "No condensation takes place above Tc."
- Analysis: This statement is correct. Above the critical temperature, the gas cannot condense into a liquid, regardless of the pressure applied. Thus, no condensation occurs above Tc.

4. **Analyzing Statement 3**:
- Statement: "Due to higher kinetic energy of the gas molecules above Tc, it is considered a supercritical fluid."
- Analysis: This statement is also correct. Above the critical temperature, the kinetic energy of gas molecules is high enough that they cannot be condensed into a liquid, leading to a state known as supercritical fluid, where distinct liquid and gas phases do not exist.

5. **Conclusion**:
- The correct statements are:
- Statement 2: "No condensation takes place above Tc." (True)
- Statement 3: "Due to higher kinetic energy of the gas molecules above Tc, it is considered a supercritical fluid." (True)

### Final Answer:
The correct statements are:
- Statement 2 and Statement 3.
