The Joule-Thomson coefficient (mu) of a gas can be mathematically represented by (a) (mu=left(frac{partial T}{partial P} ight)_{H})

The Joule-Thomson coefficient \(\mu\) of a gas can be mathematically represented by

(a) \(\mu=\left(\frac{\partial T}{\partial P}\right)_{H}\)

(b) \(\mu=\left(\frac{\partial V}{\partial P}\right)_{H}\)

(c) \(\mu=\left(\frac{\partial P}{\partial T}\right)_{H}\)

(d) \(\mu=\left(\frac{\partial P}{\partial V}\right)_{H}\).
