Q: Which of the following statements about enthalpy is true?
Solution: Enthalpy is an extensive property, meaning it depends on the amount of substance present.
Steps: 5
Step 1: Understand what enthalpy is. Enthalpy is a measure of energy in a system, often used in chemistry.
Step 2: Learn about properties of substances. Properties can be extensive or intensive.
Step 3: Know the difference between extensive and intensive properties. Extensive properties depend on the amount of substance (like mass or volume), while intensive properties do not (like temperature or density).
Step 4: Recognize that enthalpy is an extensive property because it changes when the amount of substance changes.
Step 5: Conclude that the statement 'Enthalpy is an extensive property, meaning it depends on the amount of substance present' is true.
