Front

A water molecule is composed of 2 Hydrogen atoms and 1 Oxygen atom. What is the chemical equation for water?

Back

H₂O

Front

Water is a polar molecule, which means it has a positive and a negative side. Hydrogen bonds form when:

Back

_{The positive end of one water molecule bonds to the negative end of another water molecule.}

Front

The ability of water molecules to stick to each other, creating surface tension is called:

Back

Cohesion

Front

The fact that water can stick to other substances is called:

Back

Adhesion

Front

Does water have a very high heat capacity, meaning it resists changing temperature when heat is added or removed?

Back

True

Front

True or False:

Water exists in the following states:
-Solid
-Liquid
-Gas

Back

True

Front

Why does ice float on water?

Back

When it freezes it becomes less dense

Front

Ocean surface water greatly affects global temperatures. Even in places that share the same latitude can have very different temperatures due to being near an ocean. True or False?

Back

True

Front

Ocean surface temperatures depend on:
- Salinity (how salty it is) only
- Latitude, Temperature, Salinity
- Rainfall and temperature
- Winds, sun, and moon

Back

Latitude, Temperature, Salinity

Front

What property of water allows it to be such a versatile solvent that it is often called the "universal solvent?"

Back

Polarity and cohesion
