Homework Statement
Freezing of water at 273 K and 1 atm
which of the following is true for the above thermodynamics process
p) q=0
q)w=0
r)ΔSsys<0
s)ΔU=0
t)ΔG=0
Homework Equations
none[/B]
The Attempt at a Solution
[/B]
i got r, s ,t
since the reaction happens at constant temperature,internal energy is constant
since the reaction is open so it is isobaric in nature and since the volume changes due to phase change,so work done is not zero,so heat must be exchanged(first law of thermodynamics).
randomness decreases so ΔSsys<0
but answer given is r t q
i couldn't understand please help.
