Question
For the process
H2O(I) → H2O(g)
at T = 100oC and 1 atmosphere pressure, the correct choice is
H2O(I) → H2O(g)
at T = 100oC and 1 atmosphere pressure, the correct choice is
Options
A.ᐃSsystem > 0 and ᐃSsurroundings > 0
B.ᐃSsystem > 0 and ᐃSsurroundings < 0
C.ᐃSsystem < 0 and ᐃSsurroundings > 0
D.ᐃSsystem < 0 and ᐃSsurroundings < 0
Solution
Given conditions are boiling conditions for water due to which
ᐃStotal = 0
ᐃSsystem + ᐃSsurroundings = 0
ᐃSsystem = - ᐃSsurroundings
For process, ᐃSsystem > 0
ᐃSsurroundings < 0
ᐃStotal = 0
ᐃSsystem + ᐃSsurroundings = 0
ᐃSsystem = - ᐃSsurroundings
For process, ᐃSsystem > 0
ᐃSsurroundings < 0
