State second law of thermodynamics in terms of entropy.
Advertisements
Solution 1
Statement: “The second law of thermodynamics states that total entropy of a system and its surroundings increases in a spontaneous process.”
For the process to be spontaneous,
`triangle "S"_"total" = triangle "S"_"sys" + triangle "S"_"surr"` > 0.
Solution 2
Second law of thermodynamics in terms of entropy:
The second law of thermodynamics states that, “The total entropy of the system and its surroundings (universe) increases in a spontaneous process”.
