What Entropy of the system means in Chemistry A-Level, as defined for OCR.
Definition of Entropy of the system
Check what you remember
Read the wording for your board, then hide it and explain Entropy of the system in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Changes in the entropy of the system can be predicted qualitatively by comparing the number of gaseous molecules on each side of a balanced equation.
