The Joule Thomson effect formula is below. μJT = (∂T/∂P)H. For a gas temperature that is above the inversion temperature, the μJT would be negative. The ∂P shall be always negative in this case, which means that the ∂ must be positive. Consequently, the warming of the gas will take place. check online pan application status
