#This first number is the number of questions:

29

#now are the questions

There are two common measurements of

measured air pressure). What does
760 Torr represent?

There are three types of substances
that ionize in solution (that means the

2. the molecule is probably soluble.


#69
M:3 3
<
When water evaporates, it turns to water
vapor, or steam. When water vapor cools
it turns back to water. When water is
turning to water vapor at the same rate
water vapor it turning to water, we
call this state:

#74
M:4 4
<
Both the 'ampere' and the 'coulomb'
are units of measurement in electricity.
Why is there more than one unit of
measurement?
>
1. because both men discovered something.
2. same reason we have meters and feet.
3. for convenience.
4. coulombs measure charge, amperes are the flow of charge.


#75
M:1 3
<
The atmosphere has three components: the
troposphere, the stratosphere and the

closest to the ground?

1. troposphere.
2. stratosphere.

is it before the stratosphere starts?
>
1. 2 miles.
2. 4 miles.
3. 6 miles.


#77
M:3 3
<
Why do planes going long distances fly
more than 6 miles up in the
stratosphere?
>
1. planes stay cleaner up there.
2. wind strength makes planes go faster.
3. there's no weather in the troposphere.


#78
M:3 3
<
If the troposphere is 6 miles up and the
stratosphere is above the troposphere,
how high does the stratosphere go?
>
1. 10 miles (stratosphere is 4 miles).
2. 35 miles (stratosphere is 29 miles).
3. 41 miles (stratosphere is 35 miles).


#79
M:1 4
<
How high up does the ionosphere go?
>
1. 200 miles up.
2. 280 miles up.
3. 320 miles up.
4. 420 miles up.


#80
M:4 4
<
The air we breath is made mostly of
oxygen and nitrogen. What are the
relative percentages of both?
>
1. about 5% nitrogen, 95% oxygen.
2. about 25% nitrogen, 75% oxygen.
3. about 65% nitrogen, 35% oxygen.
4. about 80% nitrogen, 20% oxygen.


#81
M:3 3
<
Oxygen is just like water in the sense
that if you cool it, it will first
become a liquid and then a solid. The
difference is that the melting and
boiling points are well below zero.

point of oxygen?
>
1. melts: -18 C, boils: 0 C.

#82
M:2 4
<
In the universe there exists a point at
which you get no colder. This point is
called absolute zero. There is nothing
at all colder than absolute zero and
in fact it is impossible to even cool
anything to that point. How cold is
absolute zero?

1. -153 Celsius.
2. -273 Celsius.
3. -350 Celsius.
4. -1252 Celsius.


#83

<
When oxygen combines with other
materials in a slow chemical process
it is called slow oxidation. When the
process is sped up, it is called:
>
1. fast oxidation.
2. ion diffusion.
3. combustion.


#84
M:1 3
<
What is fire?
>
1. reacting oxygen making light and heat.

3. a rift in the space/time continuum.


#85
M:1 2
<
Why is it easier to cause some
substances to burn only if you put
them into a fire that has already been
set?
>
1. it has to do with electron orbitals.
2. because oxygen is more reactive hot.



#86
M:7 7

and oxygen are in the air we breath
every day?
>
1. argon gas.
2. neon gas.
3. water vapor.

Some elements are exceedingly abundant
on the planet Earth, while some do not
exist in nature but must be made in a
laboratory. Magnesium is the 8th most
abundant element on the Earth's crust.
What percentage of the crust do you
think is made of the metal magnesium?
>
1. about 0.02% of the crust is magnesium.
2. about 0.32% of the crust is magnesium.
3. about 2% of the crust is magnesium.
4. about 5.22% of the crust is magnesium.


#88

We've heard of the substance ozone as in
the ozone layer around the planet that
protects us from the Ultra Violet (UV)
energy produced by the sun. What is
ozone?
>
1. a molecule: 1 neon and 1 oxygen atom.
2. 3 oxygen atoms bonded together.

#89
M:3 3
<
What percentage of the human body is
made up of water?
>
1. just 3 percent.
2. about 34 percent.

#90
M:2 3
<
With 75% of the Earth's surface covered
with water, why are there such vast
shortages in some areas threatening man?
>
1. we use it too quickly.
2. most water is full of deadly toxins.
3. most water is in the seas, not inland.
