During an adiabatic expansion process, there is no heat exchange with the surroundings. As a result, the change in enthalpy is directly related to the change in temperature. When a gas expands adiabatically, its temperature decreases, leading to a decrease in enthalpy.

How does enthalpy change during adiabatic expansion?

During adiabatic expansion, enthalpy remains constant.


What is the relationship between adiabatic expansion and enthalpy change in a thermodynamic system?

During adiabatic expansion in a thermodynamic system, there is no heat exchange with the surroundings. This leads to a change in enthalpy, which is the total heat content of the system. The enthalpy change during adiabatic expansion is related to the work done by the system and can be calculated using the first law of thermodynamics.


What is the relationship between adiabatic processes and the change in enthalpy (H)?

In adiabatic processes, there is no heat exchange with the surroundings, so the change in enthalpy (H) is equal to the change in internal energy (U). This means that in adiabatic processes, the change in enthalpy is solely determined by the change in internal energy.


What is the relationship between the adiabatic process and the change in enthalpy (H) of a system?

What is the relationship between temperature and enthalpy change for an ideal gas?

The relationship between temperature and enthalpy change for an ideal gas is described by the equation H nCpT, where H is the enthalpy change, n is the number of moles of the gas, Cp is the molar heat capacity at constant pressure, and T is the change in temperature. This equation shows that the enthalpy change is directly proportional to the temperature change for an ideal gas.


What is the difference between isentropic and isenthalpic expansion?

isenthalpic expansion is through PRDS or control valve where entropy changes. Whereas expansion through a steam turbine is isentropic one and enthalpy drops. isentropic expansion is more efficient process as compared to isenthalic one.


What is the relationship between the change in enthalpy (H), specific heat capacity (Cp), and temperature change (T) in a system?

The relationship between the change in enthalpy (H), specific heat capacity (Cp), and temperature change (T) in a system is described by the equation H Cp T. This equation shows that the change in enthalpy is directly proportional to the specific heat capacity and the temperature change in the system.


What is Thompson experiment?

It is an experiment in which the Joule-Thomson coefficient is measured. Basically, you are expanding a gas under adiabatic conditions to ensure constant enthalpy and you will notice that there will be a temperature change (most likely cooling).


Is the enthalpy change (H) independent of temperature?

No, the enthalpy change (H) is not independent of temperature. It can vary with temperature changes.
