Can somebody explain to me why the temperature gets colder when expanding through a turbine versus expanding through a valve.
Please explain with equations.

The purpose of expanding a gas through a valve or through a turbine is to convert the energy stored in the gas into mechanical or electrical energy. This can be used to power machines or generate electricity.
The main difference between expanding a gas through a valve and through a turbine is the method in which the energy is extracted from the gas. In a valve, the gas expands and does work against the resistance of the valve itself, while in a turbine, the gas expands and does work against a rotor, which is connected to a generator to produce electricity.
Expanding a gas through a valve or through a turbine results in a decrease in both temperature and pressure. This is due to the gas expanding and doing work, which results in a decrease in the internal energy of the gas.
The efficiency of expanding a gas through a valve or through a turbine is affected by several factors, including the type and design of the valve or turbine, the properties of the gas being expanded, and the operating conditions. Additionally, the efficiency can be improved by minimizing losses due to friction and turbulence.
Expanding a gas through a valve or through a turbine has a wide range of real-world applications, including power generation in gas turbines, refrigeration in air conditioning systems, and propulsion in jet engines. It is also used in industrial processes such as chemical production and oil refining.
