water that supplies wells
water that is part of the water table
all of the above
What is a solvent?
any chemical compound
a substance that can dissolve a solid or gas
a substance that can turn into water
a substance that can explode
What happens to the water after precipitation brings it to land?
Five different things can happen to it
Nothing; thats the end of that water
It becomes the universal solvent
It always goes into the ocean
What are the three states of matter that water can exist in on Earth?
solid, gas, and plasma
solid, liquid, and gas
Bose-Einstein condensate, plasma, and liquid
liquid, solid, and frozen
Waters chemical symbol is
N
Wa
Water is
a chemical compound
constantly moving
sometimes a solid, liquid, or a gas
all of the above
The water cycle is driven by the
sun
moon
clouds
oceans
The water cycle always starts in the
oceans
clouds
plants and animals
It has no starting place or ending place
The water cycle also has another name. What is it?
the nitrogen cycle
the carbon cycle
the hydrologic cycle
the moon cycle
Precipitation is another word for
breathing
ice melting

1- 1.5%
1-2%
71%
97%
Freshwater running underground are called
rivers
streams
creeks
aquifers
Because water continuously changes states from solid, liquid, and gas
We have the water cycle
We have oceans that are salty
We have rivers and lakes
We have different temperatures
Because water can dissolve many things, it is called
the great dissolver
the universal solvent
the biggest loser
the winner
After water vapor is carried high into the atmosphere, what happens to it?
It forms clouds, and air currents move them around
It keeps rising until it goes into outer space
It sublimates into ice
It magically changes back into water
95% of the Earths water is stored in its
rivers
oceans
glaciers
underground aquifers

Which of the following correctly states how the viscosities of a liquid and a gas will change with temperature?
Viscosity decreases with the increase in temperature of a liquid and decreases with the increase in temperature of a gas
Viscosity decreases with the increase in temperature of a liquid and increases with the increase in temperature of a gas
Viscosity increases with the increase in temperature of a liquid and decreases with the increase in temperature of a gas
Viscosity increases with the increase in temperature of a liquid and increases with the increase in temperature of a gas
What is the correct definition of solubility?
The rate at which a solute dissolves into a solvent
The ability of immiscible liquid droplets to disperse within a second liquid phase
The ability of solid particles to disperse throughout a liquid continuous phase
The ability of a solute to dissolve into a solvent
What is the correct definition of a pseudoplastic liquid?
A liquid which becomes less viscous over time when a constant shear stress is applied
A liquid which becomes more viscous over time when a constant shear stress is applied
A liquid which becomes less viscous as the rate of shear increases
A liquid which becomes more viscous as the rate of shear increases
