Name the five states of
matter.
Template by
Bill Arcuri, WCSD
Solid, Liquid, Gas, Plasma, Bose-Einstein
Condensate

Bill Arcuri, WCSD
What is it called when a
solid enters a liquid state?
Template by
Bill Arcuri, WCSD
Melting

What is it called when a
liquid enters the gas state?

What is it called when a gas
enters the solid state?

How fast does light travel
through a Bose-Einstein
Condensate?
Template by

The speed of a bicycle

What is the difference
between physical and
chemical properties?
Template by
Bill Arcuri, WCSD
Physical properties can
be observed without
changing the molecule,
chemical properties
cannot.
Template by
Bill Arcuri, WCSD
Explain the difference
between intensive and
extensive properties.
Template by
Bill Arcuri, WCSD
Intensive does not
depend on the size of
the sample and
extensive does.
Template by
Bill Arcuri, WCSD
What is the equation for
density?
Template by
Bill Arcuri, WCSD
Density= mass/volume
Template by
Bill Arcuri, WCSD
To what property of matter
is floating due?

Bill Arcuri, WCSD
Density
Template by
Bill Arcuri, WCSD
What variable axis is mass on, on a
density graph?
Template by
Bill Arcuri, WCSD
y-axis

Define pressure
Template by
Bill Arcuri, WCSD
The force of the gas
atoms or molecules
running into the wall of
their container

Bill Arcuri, WCSD
What is the Kinetic
Molecular Theory (not the
assumptions)?
Template by
Bill Arcuri, WCSD
The theory that explains the
over all behavior of gasses.
Template by
Bill Arcuri, WCSD
What are the main
assumptions of the Kinetic
Molecular Theory?
Template by
Bill Arcuri, WCSD
- Matter consists of small particles which have
mass
- The distances separating gas molecules is so
large that the volume of the molecules
themselves is insignificant
- Gas particles move constantly, randomly, and
rapidly
- Collisions of gas particles are completely
elastic (no energy loss).
- The temperature of gas particles is directly
related to their temperature
- Gas particles exert no force on each other,
and neither attract nor repel other gas particles
Template by
Bill Arcuri, WCSD
Describe the behavior of an
ideal gas.
Template by
Bill Arcuri, WCSD
It exactly follows the
KMT.
Template by
Bill Arcuri, WCSD
Do real gases always
adhere to the KMT?

What are the five units of
pressure?
Template by
Bill Arcuri, WCSD
atm, mm Hg, psi, torr, kPa
Template by
Bill Arcuri, WCSD
1 atm is equal to (use
another unit of pressure)…
Template by
Bill Arcuri, WCSD
760 mm Hg, 14.7 psi,
760 torr, 101.3 kPa
(any are acceptable)
Template by
Bill Arcuri, WCSD
What are Gay Lussac's and
Charles’ gas laws?
Template by
Bill Arcuri, WCSD
Gay Lussac’s:
P1/T1=P2/T2
Charles: V1/T1=V2/T2
Template by
Bill Arcuri, WCSD
What are Boyle’s and the Combined
gas laws?
Template by
Bill Arcuri, WCSD
Boyle: P1V1=P2V2
Combined:
P1V1/n1T1=P2V2/n2T2
Template by
Bill Arcuri, WCSD
What is the ideal gas law?
Template by
Bill Arcuri, WCSD
PV=nRT

A gas occupies 15.7L at 1.25atm.
What is the volume at standard
pressure?
Template by
Bill Arcuri, WCSD
19.6L
Template by
Bill Arcuri, WCSD
What is the volume of a gas
at 30ºC if it is 10.5L at
º
22 C?
Template by
Bill Arcuri, WCSD
10L
Template by
Bill Arcuri, WCSD
How many moles are needed to
create 25.0L at 105kPa and
20ºC?
Template by
Bill Arcuri, WCSD
1 mol

Bill Arcuri, WCSD
Calculate Kp for each of the two
reactions (happening in the same
flask):
2 FeSO4(s) <===> Fe2O3(s) +
SO3(g) + SO2(g)SO3(g) <===>
SO2(g) + 1/2 O2(g)
After equilibrium is reached, total
pressure is 0.836 atm and partial
pressure of oxygen is 0.0275
atm.
Template by
Bill Arcuri, WCSD
First reaction:
Kp=.163
Second reaction:
Kp=.190

number?

How many moles are in a mole of
moles?
Template by
Bill Arcuri, WCSD
602,000,000,000,000,00
0,000,000 moles

What are the units for atomic mass?
Template by
Bill Arcuri, WCSD
g/mol
Template by
Bill Arcuri, WCSD
What are the conditions of
Standard Temperature and
Pressure?
Template by
Bill Arcuri, WCSD
1atm(760 mm Hg, 14.7 psi,
760 torr, 101.3 kPa), and
273K (or 0ºC)
Template by
Bill Arcuri, WCSD
Why do balloons shrink when you put them in
liquid nitrogen?
Template by
Bill Arcuri, WCSD
Liquid nitrogen is very cool and since
gases become lesser in volume as
they lose kinetic energy (temperature),
the gases inside the balloons shrink
bringing the container along with it.
