Questions and Answers

1.

What type of reation is theDiet Coke and Mentos eruption?
- A.
  
  Physical Reaction
- B.
  
  Chemical Reaction
- C.
  
  Both Physical and Chemical Reaction
Correct Answer
C. Both pHysical and Chemical Reaction

Explanation
The Diet Coke and Mentos eruption is both a physical and chemical reaction. When Mentos candies are dropped into a bottle of Diet Coke, a physical reaction occurs as the carbon dioxide gas in the soda is released rapidly, causing a foaming eruption. This physical reaction is due to the rough surface of the Mentos candies providing nucleation sites for the carbon dioxide bubbles to form. Additionally, a chemical reaction takes place as the ingredients in the Mentos, such as gum arabic and gelatin, react with the carbon dioxide, causing even more gas to be released. Therefore, the Diet Coke and Mentos eruption involves both physical and chemical changes.

2.

Which process creates the eruption?
- A.
  
  Nulceation
- B.
  
  Substitution
- C.
  
  Nuclear Explosion
Correct Answer
A. Nulceation
3.

Will fruit-flavored, smooth-coated Mentos work in this eruption?
- A.
  
  Yes
- B.
  
  No
- C.
  
  Even better than the Mint-flavored
Correct Answer
B. No

Explanation
The answer is "No" because the question asks if fruit-flavored, smooth-coated Mentos will work in the eruption. Since the question specifically mentions a different type of Mentos than the traditional mint-flavored ones, it implies that the fruit-flavored ones may not work or may not work as well.

4.

Will more Mentos create a larger eruption?
- A.
  
  Yes
- B.
  
  No
- C.
  
  The eruptions will be the same size
Correct Answer
A. Yes

Explanation
More Mentos will create a larger eruption because Mentos candies contain tiny pits on their surface that provide nucleation sites for carbon dioxide bubbles in the soda. When Mentos are dropped into a soda bottle, the carbon dioxide in the soda rapidly forms bubbles on the surface of the Mentos, causing a rapid release of gas and creating a volcanic eruption. Adding more Mentos will increase the number of nucleation sites, resulting in a larger release of gas and a bigger eruption.

5.

Will regular tap water create an eruption when combined with two Mentos?
- A.
  
  Yes
- B.
  
  No
- C.
  
  No, but if you add more, an eruption will occur.
Correct Answer
B. No

Explanation
Regular tap water will not create an eruption when combined with two Mentos. The eruption is caused by the carbon dioxide gas in carbonated beverages, such as soda, reacting with the rough surface of the Mentos candy. Tap water does not contain carbon dioxide gas, so it will not create the same reaction. Therefore, the correct answer is no.

Rate this question:
6.

What is sublimation?
- A.
  
  The act of submerging an object under water.
- B.
  
  The expansion of an object in a fluid.
- C.
  
  The creation of bubbles on a surface on an object in a liquid.
Correct Answer
C. The creation of bubbles on a surface on an object in a liquid.

Explanation
Sublimation refers to the process of a solid directly converting into a gas without going through the liquid phase. It does not involve submerging an object under water or the expansion of an object in a fluid. The creation of bubbles on a surface of an object in a liquid is not a definition of sublimation.

How does a nozzle help the Diet Coke and Mentos eruption?
- A.
  
  It focuses the jet upward.
- B.
  
  It creates a wider stream of foam.
- C.
  
  It does assist it at all.
Correct Answer
A. It focuses the jet upward.

Explanation
A nozzle helps the Diet Coke and Mentos eruption by focusing the jet upward. When the Mentos candy is dropped into the Diet Coke, it creates a reaction that releases carbon dioxide gas. The nozzle directs this gas in a specific direction, causing it to shoot upward and create a fountain-like effect. Without the nozzle, the gas would disperse in all directions, resulting in a less dramatic eruption.

Rate this question:
8.

If an object with small rough holes on its surface is dropped into the Diet Coke, will it create an eruption?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
When an object with small rough holes on its surface is dropped into Diet Coke, it will create an eruption. This is because the carbonation in the Diet Coke reacts with the rough surface of the object, causing the release of carbon dioxide gas. The gas bubbles then rise to the surface, creating an eruption or fizzing effect.

Rate this question:
9.

Will a larger bottle of soda, produce a larger eruption?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
A larger bottle of soda will produce a larger eruption because there is more volume of carbon dioxide gas trapped inside the bottle. When the bottle is opened, the pressure is released and the gas bubbles expand, causing the eruption. With a larger volume of gas, there will be more bubbles and a bigger eruption.

Rate this question:
10.

Does the amount of Menots affect the size of the eruption?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
The correct answer is "Yes" because the amount of Menots does affect the size of the eruption. Menots are a type of volcanic material that is ejected during an eruption. The more Menots there are, the larger the eruption is likely to be. This is because the presence of a greater amount of Menots indicates a higher level of volcanic activity and pressure beneath the surface, leading to a more significant release of volcanic material during an eruption.
