Question
For eac
em 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 mixture of xenon (Xe) gas and
nitrogen (N₂) gas at 1 atm and
22° C.
1.0 g of potassium iodide (KI) and
2.0 L of pure water at 42 °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).
An additional 2.0 L of pure N₂ gas
is added to the mixture, with the
pressure kept constant at 1 atm.
The potassium iodide is dissolved in
the water.
