Question
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 (0₂) 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.
