| Abstract: | A gas distribution function for a 2D nanopore was derived, making possible calculations of thermodynamic characteristics such as pressure and heat capacity. The dependence of pressure and heat capacity on the least nanopore size was considered suggesting the presence of specific phase transitions in the gas in a certain temperature range. The phase transitions are associated with size quantization which results in “effective” interaction (attraction) between gas molecules. |
