Biomass energy is the energy produced or generated by living or extinct organisms. Plants, such as corn and soy, are the most frequent biomass materials utilized for energy. The energy produced by these organisms can be used to generate heat or power.
1. The term biomass most commonly refers to
- Inorganic matter
- Chemicals
- Ammonium compounds
- Organic matter
Answer- 4. Organic matter because biomass is a word used to describe organic materials such as wood and cereals that are grown specifically to be burned to generate heat and power.
2. Biomass also includes dead organisms.
- False
- True
- None of these
- All of these
Answer- 2. True because biomass also includes dead organisms. Biomass includes some living species, recently deceased organisms, and plant and animal by-products.
3. Biomass can be used to make ___________
- Chemicals
- Fibres
- Biochemical
- Transportation fuels
Answer: 4. Transportation fuels as Biomass can be used to make transportation fuels. It can also be used to generate renewable electricity and heat.
5. Which of the following is an example of biomass feedstock from starch crops?
- Sugar cane
- Corn Stover
- Orchard pruning
- Wheat straw
Answer: 1. Sugar cane, iron, wheat, sugar beets, and instrial sweet and potato biomass are among the grains and starch crops biomass.
6. Which of the forestry materials listed below can be utilised as biomass?
- Logging residues
- Manure
- Tallow
- Fish oil
Answer: 1. Logging residues are forestry resources that can be used as biomass. Animal by-products such as tallow, fish oil, and manure can all be used as biomass.
7. Which of the following does not serve as a source of biomass?
- Hybrid poplar
- Trap grease
- Willow algae
- Iron nails
Answer: 4. Iron nails because Energy crops such as hybrid poplar and willow algae can be used as biomass. The trap greases fall under the category of urban garbage that can be used as biomass. The biomass is not made up of iron nails.
8. _________ is made from the aerobic decomposition of sewage.
- Biomass
- Synthetic fuels
- Metal articles
- Bio fuels
Answer: 4. Bio fuels because the aerobic digestion of sewage is used to produce biofuels. The fuels that can be derived from the biomass are called bio fuels.
9. Bio ethanol, often known as __________, is a denatured alcohol.
- Ethylene
- Methylated spirit
- Ethylene glycol
- Methylene
Answer: 2. Methylated spirit because denatured alcohol is what bio ethanol is. Methylated spirit is another name for it. When consumed, it causes blindness.
10. Denatured alcohol is what bio ethanol is. Methylated spirit is another name for it. When consumed, it causes blindness.
- Acid
- Milk
- Sugar
- Alcohol
Answer: 3. Sugar. The sugar and starch components of plant products are fermented to make bio ethanol. It is first milled before being combined with water and enzymes.
11. The bio ethanol undergoes rectification in order to eliminate
- Sugar
- Impurities
- Enzymes
- Yeast
Answer: 2. Impurities. The sugar syrup and yeast are fermented after adding the water and enzymes, followed by distillation and rectification to remove contaminants.
12. The bio ethanol produced during the fermentation process has a purity of .
- 99%
- 99.7%
- 99.2%
- 99.4%
Answer: 2. 99.7%. The bio ethanol produced during the manufacturing process is 99.7% pure. The fermenting method yields the utmost purity.
13. The by-products produced during bio ethanol rectification are used as_________.
- Pig feed
- Cow feed
- Dog feed
- Sheep feed
Answer: 3. Dog Feed. The by-products collected during bio ethanol rectification are evaporated, dried, and can be utilised as dog food.
14. Bio ethanol is mixed with ________ to generate transportation fuel.
- Diesel
- Oil
- Kerosene
- Petrol
Answer: 2. Petrol. Bio ethanol is combined with petrol to generate transportation fuel. It is one of the bio ethanol’s applications.
15. The biogas is referred to as ________
- Bio ethanol
- Biodiesel
- Bio butanol
- Bio methane
Answer: 4. Bio methane. The bio methane is called the bio gas. It is primarily used in the kitchen. It is primarily made from animal faeces.
16. The carbon dioxide content of bio methane is __________.
- 30-40
- 55-60
- 32-43
- 35-45
Answer: 3. 32-43. Bio methane is the mixture of the methane, carbon dioxide, small amounts of nitrogen. The carbon dioxide is nearly of 32-43%.
17. What is a different term for biogas?
- Biobutanol
- Biodiesel
- Bio methane
- Bio ethanol
Answer: 3. Bio methane
18. The term “biomass” comes from the
- Commercial source
- Renewable energy resources
- Non Renewable resources
- None of these
Answer:2. Renewable energy resources
19. Which of the following terms is most commonly used in the field of biomass?
- Inorganic matter
- Ammonium compounds
- Chemicals
- Organic matter
Answer: 2. Organic matter
20. Which of the following components is not employed in biomass production?
- Iron nail
- Willow algae
- Hybrid poplar
- Trap grease
Answer: 1. Iron nail
21. Which of the following issues arise with the production of biomass?
- High carbon dioxide emissions
- Land degradation
- Deforestation
- All of the above
Answer: 4. All of the above
22. Which of the following sources of alcohol is the most reliable?
- Tapioca
- Nobel came
- Wood
- Barley
Answer: 4. Barley
