Examples
- The change in enthalpy of a system is equal to the amount of heat transferred during a constant pressure process.
- High pressure and temperature can significantly alter the enthalpy of a substance, making it more or less stable.
- Enthalpy is an important concept in thermodynamics, as it allows us to determine the energy of a system.
- The enthalpy of a fluid is dependent on its temperature, pressure, and composition.
- Measuring the enthalpy of combustion helps predict the maximum possible efficiency of an engine using that fuel.
