Solid
Gas
Heat
Liquid
What makes the water molecules different from any other substance on Earth? Also represented by the dotted lines on the image.
Ionic bonds
Covalent bonds
Strong bonds
Hydrogen bonds
Why does ice float?
As water freezes, it expands and its density decreases.
As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?
Water is an acid.
Water is a versatile solvent.
Water has a high heat capacity.
Water acts as a buffer.
