Multiple choice

Which conversion technology involves heating biomass in the absence of oxygen?

  1. Gasification

  2. Pyrolysis

  3. Combustion

  4. Anaerobic digestion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pyrolysis involves heating biomass in the absence of oxygen, resulting in the production of a variety of products, including bio-oil, charcoal, and gases.

Multiple choice

Which conversion technology involves the partial oxidation of biomass in the presence of a controlled amount of oxygen?

  1. Gasification

  2. Pyrolysis

  3. Combustion

  4. Anaerobic digestion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gasification involves the partial oxidation of biomass in the presence of a controlled amount of oxygen, resulting in the production of a gaseous mixture known as syngas.

Multiple choice

Which conversion technology involves the complete combustion of biomass in the presence of excess oxygen?

  1. Gasification

  2. Pyrolysis

  3. Combustion

  4. Anaerobic digestion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Combustion involves the complete combustion of biomass in the presence of excess oxygen, resulting in the production of heat and carbon dioxide.

Multiple choice

Explanation

Propane is not a common alternative fuel used in vehicles, unlike electricity, hydrogen, and natural gas.

Multiple choice

What is the primary source of heat in tandoori cooking?

  1. Charcoal

  2. Electricity

  3. Gas
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tandoori cooking traditionally uses charcoal as the primary source of heat. Charcoal provides a high and consistent temperature, which is ideal for grilling and roasting food. Electricity and gas can also be used, but they may not impart the same smoky flavor and aroma as charcoal.

Multiple choice

Which of the following is NOT a major type of fossil fuel?

  1. Coal

  2. Oil

  3. Natural Gas

  4. Uranium
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Uranium is a radioactive element used as a fuel in nuclear reactors, but it is not considered a fossil fuel, which are formed from the remains of ancient organisms.

Multiple choice

What is the traditional fuel used in a tandoor oven?

  1. Charcoal

  2. Wood

  3. Gas

  4. Electricity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Traditionally, tandoor ovens are fueled by charcoal, which provides intense heat and imparts a smoky flavor to the food.
