Questions and Answers

1.

Which of these is a unit of the absolute temperature scale?
- A.
  
  Kelvin
- B.
  
  Fahrenheit
- C.
  
  BTU
- D.
  
  Molecule
Correct Answer
A. Kelvin

Explanation
Kelvin is a unit of the absolute temperature scale. It is used in scientific and engineering calculations and is based on the absolute zero point, which is the lowest possible temperature. Unlike Fahrenheit, which is commonly used in the United States, Kelvin does not have negative values and is used in many scientific disciplines, including physics and chemistry. BTU (British Thermal Unit) is a unit of energy, and molecule is a unit of measurement for the number of atoms or particles in a substance.

Over ninety percent of the Earth's sun is made of what two elements?
- A.
  
  Uranium And Plutonium
- B.
  
  Hydrogen And Helium
- C.
  
  Neon And Argon
- D.
  
  Oxygen And Nitrogen
Correct Answer
B. Hydrogen And Helium

Explanation
The correct answer is Hydrogen and Helium. This is because the sun is primarily composed of these two elements. Hydrogen makes up about 74% of the sun's mass, while helium accounts for around 24%. These two elements undergo nuclear fusion in the sun's core, releasing a tremendous amount of energy in the form of light and heat. Other elements, including small amounts of heavier elements like oxygen and nitrogen, are also present in the sun, but in much smaller quantities compared to hydrogen and helium.

What term is used for seepage into a material?
- A.
  
  Background Noise
- B.
  
  Breakage
- C.
  
  Infiltration
- D.
  
  Blockage
Correct Answer
C. Infiltration

Explanation
Infiltration is the term used for seepage into a material. It refers to the process of water or other substances penetrating or permeating through a material, such as soil or a barrier. This term is commonly used in various fields, including geology, hydrology, and environmental science, to describe the movement of liquids or gases into a solid material.

4.

What word means the amount of energy needed to raise the temperature of a gram of water one degree?
- A.
  
  Gauss
- B.
  
  Thermophile
- C.
  
  Calorie
- D.
  
  Kelvin
Correct Answer
C. Calorie

Explanation
A calorie is the unit of measurement used to quantify the amount of energy required to raise the temperature of one gram of water by one degree Celsius. It is commonly used in the field of nutrition to measure the energy content of food. The other options, Gauss and Kelvin, are units of measurement for magnetic flux density and temperature, respectively. Thermophile refers to an organism that thrives in high temperatures.

5.

What word means leakage out of a system?
- A.
  
  Baud
- B.
  
  Exfiltration
- C.
  
  Abruption
- D.
  
  Cleaving
Correct Answer
B. Exfiltration

Explanation
Exfiltration is the correct answer because it refers to the act of unauthorized data leaving a system or network. It involves the intentional extraction or leakage of sensitive information, typically by an attacker or insider threat. This term is commonly used in the context of cybersecurity and data breaches, highlighting the importance of protecting systems and networks from such unauthorized data exfiltration.

6.

What units are combined in sequence to make proteins?
- A.
  
  Vitamins
- B.
  
  Sugars
- C.
  
  Amino Acids
- D.
  
  Steroids
Correct Answer
C. Amino Acids

Explanation
Proteins are made up of amino acids, which are the building blocks of proteins. Amino acids are combined in a specific sequence to form proteins. Vitamins, sugars, and steroids do not play a direct role in the formation of proteins.

Rate this question:
7.

Which of these is a carbohydrate?
- A.
  
  Enzyme
- B.
  
  Lipid
- C.
  
  Sugar
- D.
  
  Protein
Correct Answer
C. Sugar

Explanation
Sugar is a carbohydrate because it is a type of simple carbohydrate known as a monosaccharide. Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms, and they serve as a major source of energy for the body. Sugars, such as glucose and fructose, are examples of simple carbohydrates that are easily broken down and absorbed by the body for energy. Therefore, sugar is the correct answer as it falls under the category of carbohydrates.

Rate this question:
8.

Which one is an element rather than a compound?
- A.
  
  Ammonia
- B.
  
  Carbon Monoxide
- C.
  
  Acetic Acid
- D.
  
  Gold
Correct Answer
D. Gold

Explanation
Gold is an element rather than a compound because it consists of only one type of atom, specifically gold atoms. Compounds, on the other hand, are formed when different elements chemically combine together. Ammonia, Carbon Monoxide, and Acetic Acid are all compounds as they are composed of multiple elements.

Rate this question:
9.

One of what unit of volume equals 0.95 litres?
- A.
  
  Gill
- B.
  
  Gallon
- C.
  
  Quart
- D.
  
  Pint
Correct Answer
C. Quart

Explanation
A quart is a unit of volume that equals 0.95 liters. It is commonly used in the United States to measure liquid capacity.

Oranges are a good source of which vitamin?
- A.
  
  Vitamin E
- B.
  
  Vitamin A
- C.
  
  Vitamin C
- D.
  
  Vitamin K
Correct Answer
C. Vitamin C

Explanation
Oranges are a good source of Vitamin C. Vitamin C is an essential nutrient that helps support the immune system, promotes the absorption of iron, and acts as an antioxidant in the body. Oranges are particularly known for their high Vitamin C content, making them a popular choice for boosting immunity and maintaining overall health.

11.

Which of these is a compound?
- A.
  
  Carbon Dioxide
- B.
  
  Potassium
- C.
  
  Sodium
- D.
  
  Helium
Correct Answer
A. Carbon Dioxide

Explanation
Carbon Dioxide is a compound because it is made up of two different elements, carbon and oxygen. It is a chemical compound that is formed when carbon atoms bond with two oxygen atoms. In contrast, Potassium, Sodium, and Helium are all elements and not compounds because they consist of only one type of atom.

Rate this question:
12.

Which carbon compound does "CO2" stand for?
- A.
  
  Carbon Carbonate
- B.
  
  Carbon Monoxide
- C.
  
  Carbon Dioxide
- D.
  
  Carbon Tetrachloride
Correct Answer
C. Carbon Dioxide

Explanation
The correct answer is Carbon Dioxide because "CO2" is the chemical formula for carbon dioxide. Carbon dioxide is a colorless gas that consists of one carbon atom bonded to two oxygen atoms. It is a common greenhouse gas and is produced by the combustion of fossil fuels and other industrial processes.

With what element does hydrogen combine to make water?
- A.
  
  Oxygen
- B.
  
  Helium
- C.
  
  Sodium
- D.
  
  Carbon
Correct Answer
A. Oxygen

Explanation
Hydrogen combines with oxygen to make water. This is because water is composed of two hydrogen atoms bonded to one oxygen atom. Oxygen is highly electronegative, meaning it has a strong attraction for electrons, while hydrogen is electropositive, meaning it has a tendency to lose electrons. This creates a polar covalent bond between the hydrogen and oxygen atoms, resulting in the formation of water molecules.
