Abstract

The liquid-vapor coexistence boundary of submonolayer CH4 adsorbed on graphite was mapped out in an extensive ac heat-capacity study. The order-parameter exponent that describes the shape of the liquid-vapor coexistence boundary was found to be 0.127 0.020. This is in good agreement with 18, the exact value calculated for a two-dimensional Ising-model system.
