The figure shows the entropy of a system as
a function of temperature for two constant pressures, across
a first-order phase transition. If the system exhibits a
coexistence line with a slope dT/dp > 0 in the phase diagram,
then we can establish that (check all that apply):
(a) The sign of the entropy change in isothermal conditions is
positive when induced increasing pressure.
(b) The sign of the temperature change in isentropic
conditions is negative when induced by decreasing pressure.
(c) P, < P2
(d) The volume change at the exothermic transition is positive.
(e) The transition driven by decreasing pressure is endothermic.
