Can gas be adsorbate?
The physical adsorption of gases on a solid surface increases with decreasing temperature and increasing pressure. Unlike chemisorption, physical adsorption may lead to surface coverage by more than one layer of adsorbate, meaning that pores can be filled by the adsorbate for pore volume measurement.
