For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System A liter of seawater at 15°C. A 0.35 M solution of sucrose in water, and a beaker of pure water, both at 37.°C. 20. L of pure oxygen (O₂) gas and 20.0 L of pure carbon dioxide (CO₂) gas, both at 5 atm and 22°C. Change The seawater is passed through a reverse-osmosis filter, which separates it into 750. mL of pure water and 250. mL of brine (very salty water). The solution is put into a semipermeable bag immersed in the water, and 50. mL of pure water flows through the bag into the sucrose solution. The gases are mixed, with the pressure kept constant at 5 atm. X AS CAS<0 AS = 0 AS > 0 not enough information CAS<0 AS=0 AS > 0 not enough information AS < 0 AS = 0 AS > 0 not enough information 15 ?
