Question

Enthalpy is ________?

1) the energy available to do work
2) the total energy content of a system
3) named after J. Willard Gibbs
4) the energy available to do work and the total energy content of a system
5) All of these are correct.

Answer 1

Enthalpy is the total energy content of a system, defined as the sum of the system's internal energy and the product of its pressure and volume.

Step-by-step explanation:

Enthalpy is the total energy content of a system. It is defined as the sum of the system's internal energy and the product of its pressure and volume. Enthalpy is a state function, meaning that it only depends on the initial and final states of the system and not on the path taken to reach those states.
