The charge-imbalance voltage in a superconductor carrying a current in the presence of a temperature gradient is calculated from the Boltzmann equation in the clean limit. We demonstrate why the Green's-function approach in the dirty limit, first performed by Schmid and Schoem, generates the same Boltzmann-like equation for the distribution function. In addition, the charge-imbalance voltage in the absence of an impressed current is calculated. It is shown to depend on del/sup 2/T+(delT)/sup 2//T, and not solely on (delT)/sup 2/. The calculations are limited to the temperature regime near T/sub c/, such that ..delta..<
