A mixture with x₂
= 0.70 in a closed isothermal piston cylinder at 100°C and 1000 mm Hg is depressurized to 800 mm Hg. What are the initial and final states of the system?


a. saturated mixture → superheated vapor

b. subcooled liquid → saturated liquid

c. saturated mixture → subcooled liquid

d. superheated vapor → saturated vapor
