-A water molecule is composed of 2 H atoms and 1 O atom. What is the chemical equation for water?
HO
H2O
H3O
H2O2
Water is a polar molecule, which means it has a positive and a negative side. Hydrogen bonds form when:
The positive end of one water molecule bonds to the positive end of another water molecule.
The negative end of one water molecule bonds to the negative end of another water molecule.
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:
Cohesion
Adhesion
Insulation
Ph
The fact that water can stick to other substances is called:
Ph
Adhesion
Cohesion
Insulation
True or False:
Heat is energy produced by the random vibrations of atoms or molecules.
True
False
Heat Capacity is a measure of the heat required to raise the temperature of 1g of a substance by 1°C.
So...
True or False:
Water has a very high heat capacity, which means it resists changing temperature when heat is added or removed.
True
False
True or False:
Water exists in the following states:
-Solid
-Liquid
-Gas
True
False
Why does ice float on water?
When it freezes it becomes less dense
When it freezes it becomes more dense
When it freezes its density stays the same
True or False:
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
False
Ocean surfaces temperatures depend on:
Salinity (how salty it is) only
Latitude, Temperature, Salinity
Rainfall and temperature
Winds, sun, and moon
