  1. C 4 .2 mole of He is mixed with more or Ne dearly s con sp numg to The apour pressure P of a solid at temperature T is expressed by InP-23 (3863/T) and hat of liquid phase is In P=19_(3063m the triple point (in Kelvin) of the material is 2001 put Gate 2007 P a)185 K b) 190 K 2ol6 csm c) 195 K d) 200 K 0 6 Two gases separated by an impermeable but movable partition are allowed to freely exchange energy. At equilibrium, the two sides wil have the same Gate physics 2013 (A) pressure and temperature (B) volume and temperature (C) pressure and volume (D) volume and energy
