Internal energy is _of path.

Correct answer: A. Independent

  • A. Independent
  • B. Dependent
  • C. Highly dependent
  • D. Not enough information

Explanation

Option A: The internal energy of a system is independent of the path taken to reach a particular state. In other words, the internal energy only depends on the initial and final states of the system, regardless of the specific process or pathway used to transition between them. This concept is based on the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.Option B: Dependent: This option suggests that the internal energy of a system depends on the specific path taken to reach a certain state. In this case, the internal energy would not only be influenced by the initial and final states but also by the specific process or pathway used to transition between them. However, this is not the case according to the principles of thermodynamics.Option C: Highly dependent: This option implies that the internal energy of a system is significantly influenced by the path taken. It suggests that the specific process or pathway used to transition between states has a strong impact on the internal energy of the system. However, this is not accurate as the internal energy is path-independent.Option D: Not enough information: This option indicates that there is insufficient information provided to determine whether the internal energy of a system is independent or dependent on the path. Without more context or knowledge, it is difficult to make a definitive conclusion.

About First Law of Thermodynamics

The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
