## Introduction to Joule-Thomson Coefficient

The Joule-Thomson coefficient (μ) describes the change in temperature of a gas as it expands or is compressed at constant enthalpy. This formula calculates the Joule-Thomson coefficient based on the initial and final temperatures and pressures of the gas. In this formula, μ represents the Joule-Thomson coefficient, T1 is the initial temperature, T2 is the final temperature, P1 is the initial pressure, and P2 is the final pressure.

## Parameters:

• `T1` = initial temperature of the gas (in Kelvin)
• `T2` = final temperature of the gas (in Kelvin)
• `P1` = initial pressure of the gas (in Pascals)
• `P2` = final pressure of the gas (in Pascals)

## Output:

• `μ` = Joule-Thomson coefficient

## Data validation

Ensure temperatures are in Kelvin and pressures are in Pascals.
