The correct Answer is:
To solve the question, we need to analyze both statements regarding enthalpy (H) and entropy (S) in thermodynamics. ### Step-by-Step Solution: 1. **Understanding Enthalpy and Entropy**: - Enthalpy (H) is a measure of the total heat content of a system, while entropy (S) is a measure of the disorder or randomness in a system. - Both properties are related to the amount of substance present in the system. 2. **Analyzing Statement 1**: - Statement 1 claims: "Enthalpy (H) and entropy (S) both are extensive properties." - Extensive properties are those that depend on the amount of substance in the system. Since both enthalpy and entropy increase with an increase in mass, this statement is **true**. 3. **Analyzing Statement 2**: - Statement 2 claims: "Both are independent of mass." - This statement contradicts the definition of extensive properties. Since enthalpy and entropy are dependent on the mass of the substance, this statement is **false**. 4. **Conclusion**: - Statement 1 is true, and Statement 2 is false. Therefore, the correct answer is that Statement 1 is true, and Statement 2 is false. ### Final Answer: - Statement 1 is true, and Statement 2 is false.
