A water molecule is composed of 2 H atoms and 1 O 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.

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

True or False:

Heat is energy produced by the random vibrations of atoms or molecules.

Back

True

Front

Does water have a 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

Does ocean surface water greatly affect global temperatures, causing places at the same latitude to have different temperatures due to proximity to an ocean?

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
