Why does helium lose enthalpy faster when cooled at a high constant pressure? Thank you.

Enthalpy change is a measure of the energy absorbed or released during a chemical reaction or physical process. It is also known as heat of reaction or heat of formation.
Enthalpy change is calculated by taking the difference between the enthalpy of the products and the enthalpy of the reactants. This can be represented by the equation ΔH = Hproducts - Hreactants.
Enthalpy change is important for Helium liquefaction because it is a crucial factor in determining the efficiency of the process. Helium has a low boiling point and requires a large amount of energy to be liquefied. Therefore, understanding and optimizing the enthalpy change is essential for efficient liquefaction.
The main factors that affect enthalpy change for Helium liquefaction include the pressure and temperature of the system, as well as the specific properties of the Helium gas being used, such as its purity and initial temperature.
Enthalpy change can be controlled during Helium liquefaction by adjusting the pressure and temperature of the system, as well as using a pure and cold helium gas as the starting material. Additionally, proper insulation and heat exchange methods can also help to control and optimize the enthalpy change during the process.
