Estimate the final temperature of a mole of gas at 200.0 atm and 19.0°c as it is forced through a porous plug to a final pressure of 0.95 atm. the joule-thomson coefficient of the gas is 0.13 k atm-1.

Answer : The final temperature of gas is 266.12 K

Explanation :

According to the Joule-Thomson experiment, it states that when a gas is expanded adiabatically from higher pressure region to lower pressure region, the change in temperature with respect to change in pressure at constant enthalpy is known as Joule-Thomson coefficient.

The formula will be:

or,

As per question the formula will be:

  .........(1)

where,

= Joule-Thomson coefficient of the gas =

= initial temperature =

= final temperature = ?

= initial pressure = 200.0 atm

= final pressure = 0.95 atm

Now put all the given values in the above equation 1, we get:

Therefore, the final temperature of gas is 266.12 K
