Physical Properties of Water
Structure of ice at 0oC
- liquid water density = 1 g/ml
- ice density = 0.92 g/ml
Heat of Sublimation of ice at 0oC is 47 kJ.mol-1
- ~ 87% of energy used to disrupt hydrogen bonds
Heat of Fusion of ice (6 kJ.mol -1)
- Liquid water has ~15% fewer hydrogen bonds than ice at 0oC
