1. Why do we need a universal container? *

In Mole Concept 01 Video, at 0:32 of the video.

A: To somehow measure a single atom

B: To measure billions of atoms

C: To fill with boring Canadian Videos

D: To mass the lightest box

E: None of the choices are correct

2. What is the trick to measuring a single atom and getting relative (based on others) mass? *

video 1

A: Each universal indicator has different gases.

B: Each universal container must have the same number of particles.

C: Each universal container has the same gas

D: Each universal container must have atoms

E: None of the choices are correct.

3.What accounts for the volume of a gas being able to expand or contract. *

At about 3:20 of the video 1.

A: The size of the container.

B: The size of the atoms

C: The space between particles.

D: All of the above

E: None of the above

4. In the concert hall, people do not sit on top of each other, what fixes the number of seats in a theater besides the size if the theater? *

video 1

A: The number of people

B: The price per seat

C: The pressure and temperature.

D: The pressure and volume.

E: None of the choices

5. How can a theater hold the same number of people no matter what their size is? *

video 1

A: Because of the needed space between the seats, there is a fixed number of seats.

B: The seats have expandable cushions

C: Some smaller folks can squeeze into the space between the larger folks.

D: Because the theater can bring out folding chairs if need be.

E: None of the choices.

6. What are the three factors can be used to describe a universal container? *

video 1

A: Temperature, Pressure, and Volume.

B: Temperature, pressure, and size

C: Pressure, Temperature, density

D: Elbow room, size of seat, and temperature.

E: None of the choices.

7. Why is it that these gas particles can have more than one atom per particle and still follow our universal container idea? *

AT 3:57 of Mole Concept Video 02!

A: Because whoopie makes more seats.

B: Because these aliens have the same pressure and temperature.

C: Because the aliens are all the same volume.

D: Because they must fit on one seat.

E: None of the choices

8. Why would we expect one volume of hydrogen and one volume of chlorine to make one volume of hydrogen chloride? *

AT 7:18 of Mole Concept Video 02!

A: Same volume equals the same number of particles if temperature and pressure are the same.

B: The number of particle per seat change when a chemical reaction occurs.

C: Because the size of each atoms are the same.

D: Because the bags only hold a max of 2 atoms.

E: None of the choices

9. What doesn't the mystery meat theory work? *

AT 2:09 of Mole Concept Video 03!

A: I do not like mice burgers

B: Atoms are not created nor destroyed

C: The second bun truck is empty

D: There are twice as many burgers in burger truck than in the bun truck

E: None of the answers are correct

10. How did Avogodros Hypothesis solve the problem? *

video 3

A: He did so by saying each "molecule" must have different volumes based on size.

B: He said that each "molecule" must have same kinetic energy.

C: He said that each "molecule" has the same volume when temperature and pressure are not constant.

D: He did by saying that each "molecule" could have 2 or more atoms

E: None of the choices are correct.

Are you hungry for hamburgers now?

11. What is the best option to determine the mass of different type of atoms?

Start at 7:02 of the 4th video,

Count a tremendous amount of atoms, mass them and divide the mass by this number

Comparing the mass of single atoms

Comparing the mass of large number of different atoms

Comparing the mass of equal numbers of different atoms

Clear selection

12. True Or False. The relative mass of 2 different atoms in containers with different number of atoms will always simplify to the relative mass of the 2 single different atoms

True

Fasle
