Why does ice float on water?
Ice has a higher density than water.
Ice has a lower density than water.
The hydrogen bonds in ice are shorter.
The hydrogen bonds in ice are longer.
What is the significance of water's high heat of vaporization?
It indicates that water can absorb a lot of heat before it begins to evaporate.
It means water evaporates quickly.
It suggests that water is a poor coolant.
It shows that water has a low specific heat.
What role do hydrogen bonds play in DNA structure?
They form the backbone of the DNA molecule.
They connect the DNA base pairs together.
