Anomalous properties of water Flashcards
1
Q
Name the 2 anomalous properties of water
A
Higher than expected boiling and melting point
Solid water is less dense that liquid water
2
Q
Why does water have a higher than expected boiling point?
A
Strong hydrogen bonds holding the water molecules together
A lot of energy is needed to break the hydrogen bonding
3
Q
Why is solid water less dense than liquid water?
A
H₂O molecules form hydrogen bonds between each other
Arrange themselves into an open lattice structure
Causes the molecules in ice to be further apart from each other
Hence why it floats
4
Q
What is the common cause of the anomalous properties?
A
Hydrogen bonding
