Water Flashcards
1
Q
Why does water have higher melting/boiling point than expected?
A
Water has hydrogen bonds and London forces
Hydrogen bonds are the strongest IMF so therefore they require more energy to break
2
Q
Why is solid less dense than liquid (ice floats on water)?
A
When water forms ice, it forms an open lattice with the water particles spaced further apart than in liquid water
This is less dense than liquid water so floats
