Which of the following statements is true regarding enthalpy changes?
Enthalpy changes are path-dependent.
Enthalpy is a state function.
Enthalpy cannot be measured directly.
All of the above.
Enthalpy is a state function, meaning its change depends only on the initial and final states, not the path taken.

Q: Which of the following statements is true regarding enthalpy changes?
Solution: Enthalpy is a state function, meaning its change depends only on the initial and final states, not the path taken.
Steps: 4
Step 1: Understand what enthalpy is. Enthalpy is a measure of energy in a system, often related to heat changes during chemical reactions.
Step 2: Learn about state functions. A state function is a property that depends only on the current state of the system, not how it got there.
Step 3: Recognize that enthalpy is a state function. This means that the change in enthalpy (ΔH) only depends on the initial and final states of the system.
Step 4: Conclude that the path taken (the process or steps in between) does not affect the change in enthalpy.
