Edexcel IAL Chemistry A2 12.3 Entropy, temperature and physical state
Sketch a rising entropy–temperature curve with vertical steps at melting and boiling, then use state and molecular complexity when ordering standard values.
How this is tested
- Sketch entropy against temperature with upward jumps at melting and boiling points.
- Order molar entropies using physical state, temperature and molecular complexity.
