Questions and Answers

1.

C&B Safety Resource Manual, February
2.

Oxidation is a chemical process to remove flames from a fire
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is incorrect. Oxidation is not a process to remove flames from a fire. In fact, oxidation is a chemical reaction that involves the addition of oxygen to a substance or the removal of hydrogen from a substance. It often produces heat or flames, which can contribute to the burning of a fire rather than extinguishing it. Therefore, the correct answer is false.

3.

Molecules move about freely in a solid
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
In a solid, molecules are tightly packed and held in fixed positions by strong intermolecular forces. This restricts their movement and prevents them from moving about freely. Therefore, the correct answer is false.

4.

Heat helps molecules to move about rapidly in a solid and liquids
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Heat is a form of energy that increases the kinetic energy of molecules in a substance. When heat is applied to a solid or liquid, the molecules gain energy and start moving more rapidly. This increased movement allows the molecules to overcome the intermolecular forces holding them together, causing the substance to melt or evaporate. Therefore, it is true that heat helps molecules to move about rapidly in solids and liquids.

As long as there is plenty of ___________ available, the fire continues to grow and more flame is produced
- A.
  
  Fuel
- B.
  
  Molecules
- C.
  
  Oxygen
Correct Answer
C. Oxygen

Explanation
Oxygen is necessary for combustion to occur. In the presence of oxygen, fuel can undergo a chemical reaction called oxidation, which releases heat and light, resulting in a fire. As long as there is an abundant supply of oxygen, the fire will continue to grow because it provides the necessary conditions for the combustion process to sustain and produce more flame.

Rate this question:
6.

A fuel has to be in a ___________ state for a fire to start
- A.
  
  Solid
- B.
  
  Liquid
- C.
  
  Vapor
Correct Answer
C. Vapor

Explanation
In order for a fire to start, a fuel needs to be in a vapor state. Fire requires a flammable substance to be in a gaseous form, where it can mix with oxygen in the air and ignite when exposed to a heat source. Solids and liquids typically do not readily vaporize and therefore do not support combustion as easily as vapors do.
