Determine Internal Energy Change of Hydrogen
On the change of internal energy of hydrogen
If you want to understand the change of internal energy of hydrogen, you must study the rationale and examine the situation. Internal energy, the sum of the internal energy of a substance is also related to the change of molecular kinetic energy and potential energy.
Hydrogen, with its unique characteristics, has different internal energy changes under various conditions. When the temperature rises and falls, the molecular kinetic energy of hydrogen will change accordingly. When the temperature rises, the molecular thermal motion intensifies, the kinetic energy increases, and the internal energy also increases; when the temperature decreases, the molecular motion slows down, the kinetic energy decreases, and the internal energy decreases.
And the change of pressure also affects the internal energy of hydrogen. When the pressure increases, the molecular spacing narrows, and the potential energy changes, which in turn causes the internal energy to change. If the pressure increases the interaction between molecules, the potential energy increases, and the internal energy also rises; conversely, when the pressure decreases, the molecular spacing increases, the potential energy decreases, and the internal energy decreases.
Furthermore, the conversion of the state of matter has a huge impact on the change of the internal energy of hydrogen. From gas to liquid, or from liquid to solid, the arrangement and interaction of molecules change, and the internal energy must be different. When gasification, heat is required to increase the internal energy, so that the molecules can break free; when liquefaction or solidification, heat is released, and the internal energy decreases.
To accurately determine the internal energy change of hydrogen, it is necessary to rely on scientific methods, physical principles, and sophisticated instruments to measure its temperature, pressure, and other parameters. Only through rigorous calculation and analysis can we understand the internal energy change.
