How joule Thomson experiment lead to coefficient?
The Joule Thomson experiment involves measuring the change in temperature of a gas as it expands through a throttle valve. The Joule Thomson coefficient is defined as the temperature change per unit pressure drop. By quantifying the temperature change in relation to the pressure drop, scientists can determine the Joule Thomson coefficient for a specific gas under certain conditions.
How do you calculate joule kelvin inversion temperature of hydrogen?
use the T=2a/(bk) equation shown in the first link, plugging in a and b values found in the second link. proofs are shown in the joule-thomson expansion wikipedia page as well as the van der waals equation of state page.
Why joule Thomson coefficient is zero for ideal gases?
The Joule-Thomson coefficient is zero for ideal gases because ideal gases do not exhibit any intermolecular forces that would cause them to deviate from ideal behavior. As a result, there is no energy exchange during expansion or compression, leading to a zero Joule-Thomson coefficient for ideal gases.
What are the applications of joule Thomson effect?
The Joule-Thomson effect is used in refrigeration systems to cool gases by expanding them through a small valve. It is also used in natural gas processing to control the temperature of gases during transportation. Additionally, it is utilized in cryogenics to produce low temperatures for scientific research and medical applications.
Why hydrogen and helium does not satisfy joule Thomson effect?
As the gs flow from high pressure to low pressur using the porus plug the temperature of the gas increases as the pressure of the gas decreases. As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas. Formula h=u+pv h--- enthalpy u-- internal energy p--pressure v---volume
Joule Thomson effect is temperature dependent or not?
The Joule-Thomson effect is temperature dependent. It describes the change in temperature of a gas as it expands or is compressed without doing external work. If the gas undergoes adiabatic expansion (no heat exchange with surroundings), its temperature will change depending on its initial temperature, pressure, and the nature of the gas.
How is the Joule-Thomson effect calculated in thermodynamics?
The Joule-Thomson effect is calculated in thermodynamics by using the Joule-Thomson coefficient, which is the rate of change of temperature with pressure at constant enthalpy. This coefficient is determined by taking the partial derivative of temperature with respect to pressure at constant enthalpy. The formula for the Joule-Thomson coefficient is given by (T/P)H, where is the Joule-Thomson coefficient, T is temperature, P is pressure, and H is enthalpy.

Why do hydrogen and helium get having very low temperatures warmed up instead of cooling in joule-thomson method?
There is for every gas a point called the inversion temperature. Above this temperature, the gas exhibits a reverse Joule-Thompson effect and warms on expansion instead of cooling. The inversion temperatures for hydrogen and helium are quite low compared to those of most other gases.

What is the value of joule Thomson coefficient for Natural gas?
The Joule-Thomson coefficient for natural gas can vary depending on the specific composition of the gas. Generally, it is around 0.25 K/bar at room temperature and pressure for most natural gas compositions. However, this value can change with different operating conditions and gas compositions.
What are the applications of Thomson effects?

Significance of joule Thomson effect?
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).
Why does the gas in the refrigerator cause cooling on expansion?
When the gas in a refrigerator expands, it absorbs heat energy from the surroundings to compensate for the decrease in pressure. This absorption of heat energy results in a decrease in temperature, causing the refrigerator to cool. This process is known as the Joule-Thomson effect.
