QuestionAnswer
The K12 lessons define [...] as the tendency of any system to move toward maximum randomness. The K12 lessons define entropy as the tendency of any system to move toward maximum randomness.
Entropy is really energy that can not be used to do any [..]. Entropy is really energy that can not be used to do any work.
The symbol for Entropy is a [...]. The symbol for Entropy is a capital S.
A [...] entropy change means that entropy has increased. A positive entropy change means that entropy has increased.
