Greater heat capacity
WebAug 21, 2015 · Constant Pressure is of no meaning in heat containing capacity. But the fact is: when heat is added, system pressure raises leading to expansion. During expansion, some of energy is expelled i.e. transported to boundary/ periphery and resides over the boundary as potential energy between the system and neighbour/ surrounding. http://complianceportal.american.edu/which-of-the-following-has-the-greatest-heat-capacity.php
