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 mixture of oxygen (O₂) gas and
hydrogen (H₂) gas at 3 atm and
7°C.
A liter of seawater at 15°C.
300 mL of a solution made from
sodium iodide (Nal) dissolved in
water.
Change
An additional 2.0 L of pure H₂ gas
is added to the mixture, with the
pressure kept constant at 3 atm.
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).
0.5 g of Nal crystallizes out of the
solution, without changing the
temperature.
