Changes in the surface area of a Wyoming sub-bituminous coal with progressive extraction have been investigated. Surface areas were determined from CO, adsorption isotherms at 196 K using the BET equation with 9.234 nm2 for the molecular cross-sectional area of the CO, molecule at 196 K. Surface are
