This term refers to general charcoal production.
- A.
A.) carbonization
- B.
B.) wood hydrolysis
- C.
C.) wood saccharification
- D.
D.) destructive distillation of wood
Correct Answer
A. A.) carbonizationExplanation
Carbonization is the process of converting organic material, such as wood, into carbon or charcoal through the application of heat in the absence of air. This term accurately describes the general production of charcoal, where wood is heated to high temperatures, causing it to release volatile compounds and leaving behind carbon-rich residue. Wood hydrolysis and wood saccharification involve the breakdown of wood into sugars, which is not the same as charcoal production. Destructive distillation of wood is a similar process to carbonization, but it specifically refers to the production of chemicals and fuels from wood, rather than charcoal.Rate this question:

C.) Second statement is true. First statement is false.
- D.
D.) All statements are false.
Correct Answer
C. C.) Second statement is true. First statement is false.Explanation
The first statement, "Charcoal is not a pyroligneous residue," is false because charcoal is actually a type of pyroligneous residue. Pyroligneous residue is the byproduct of burning wood or other plant material, and charcoal is specifically produced by heating wood in the absence of oxygen. Therefore, charcoal can be considered a type of pyroligneous residue. The second statement, "Cordwood is a type of wood fuel," is true because cordwood refers to a stack of cut and split firewood that is used as a fuel source for heating or cooking.Rate this question:

- B.
B.) First statement is true. Second statement is false.
- C.
C.) All statements are false.
- D.
D.) All statements are true.
Correct Answer
C. C.) All statements are false.Explanation
The given answer is correct because both statements are false. The first statement states that wood hydrolysis is otherwise referred to as carbonization, which is incorrect. Wood hydrolysis is a chemical process that breaks down wood into its constituent parts using water. Carbonization, on the other hand, is a process that involves heating wood in the absence of oxygen to produce charcoal. The second statement states that Batikuling is not the most preferred species for wood carving, which is also false. Batikuling wood is actually highly valued for its fine grain and ease of carving, making it a popular choice for wood carving and sculpture. Therefore, both statements are false.Rate this question:

It is the most important process of preparing fibers to accept color.
- A.
A.) dry cleaning
- B.
B.) wood hydrolysis
- C.
C.) mordanting
- D.
D.) wood saccharification
Correct Answer
C. C.) mordantingExplanation
Mordanting is the process of treating fibers with a mordant, which is a substance that helps the fibers accept and retain color. This is important because without mordanting, the color would not adhere properly to the fibers and would wash out easily. Mordanting ensures that the color is more vibrant and long-lasting. Dry cleaning, wood hydrolysis, and wood saccharification are not related to preparing fibers for accepting color, so they are not the correct answer.Rate this question:
