elld
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 nitrogen (N2) gas and
carbon dioxide (CO2) gas at 1 atm
and 8°C.
Change
An additional 2.0 L of pure CO2
gas is added to the mixture, with the
pressure kept constant at 1 atm.
AS
AS < 0
AS = 0
AS > O
A solution made of sodium chloride
(NaCl) in water, at 71°C.

50. mL of pure water is added to
the solution.
AS > O
A 0.35 M solution of sucrose in
water, and a beaker of pure water,
both at 37.°C.
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.
