Definition of Entropy change and the T∆S term
Check what you remember
Read the wording for your board, then hide it and explain Entropy change and the T∆S term in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The entropy term is written T∆S, so its sign follows ∆S: a positive ∆S gives a positive T∆S, and a negative ∆S gives a negative T∆S.
