Oil is that viscous and liquid material that came from animals, vegetables, or petrochemical. It is a component of hydrocarbons and it is extremely popular. So, what's up with your knowledge base? You think you can pass this?

Questions and Answers

1.

Oil is a viscous liquid at..... Temperature
- A.
  
  Ambient
- B.
  
  High
- C.
  
  Low
- D.
  
  Cold
Correct Answer
A. Ambient

Explanation
Oil is a viscous liquid at ambient temperature because ambient temperature refers to the temperature of the surrounding environment. In most cases, the ambient temperature is neither too high nor too low, making it ideal for oil to maintain its liquid form. At high temperatures, oil can become less viscous and may even evaporate. On the other hand, at low or cold temperatures, oil can become thicker and more solid, making it difficult to flow. Therefore, ambient temperature provides the optimal conditions for oil to retain its viscosity as a liquid.

The hydrophobic nature of oil means?
- A.
  
  It is water loving
- B.
  
  It is fat loving
- C.
  
  It is water-repellent
- D.
  
  It is bibulous
Correct Answer
C. It is water-repellent

Explanation
The correct answer is "It is water-repellent." Oil is hydrophobic, meaning it repels or does not mix with water. This is because oil molecules are nonpolar, while water molecules are polar. Due to the difference in polarity, oil and water do not mix and oil forms separate droplets or layers when in contact with water. This property of oil being water-repellent is commonly observed in everyday situations, such as oil floating on the surface of water or oil-based products not easily mixing with water.

Oil can be derived from which of the following?
- A.
  
  Water
- B.
  
  Atmosphere
- C.
  
  Alcohol
- D.
  
  Hydrocarbons
Correct Answer
D. Hydrocarbons

Explanation
Oil is derived from hydrocarbons because oil is a fossil fuel that is formed from the remains of plants and animals that lived millions of years ago. These remains, under high pressure and temperature, undergo a process called diagenesis and transform into hydrocarbons. Hydrocarbons are organic compounds that consist of hydrogen and carbon atoms. Oil is a mixture of various hydrocarbons, such as alkanes, cycloalkanes, and aromatic compounds. Therefore, hydrocarbons are the source of oil.

The following are types of oil, except?
- A.
  
  Organic oil
- B.
  
  Inorganic oil
- C.
  
  Mineral oil
- D.
  
  Natural oil
Correct Answer
B. Inorganic oil

Explanation
Inorganic oil is not a valid type of oil. Oil is a natural substance that is derived from organic materials such as plants, animals, or minerals. Inorganic substances, on the other hand, are derived from non-living matter such as rocks or metals. Therefore, inorganic oil does not exist.

Oil is used in......?
- A.
  
  Heat transfer
- B.
  
  Lubricants
- C.
  
  Religion
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Oil is used in heat transfer as it has high thermal conductivity, allowing it to efficiently transfer heat from one place to another. It is also used as lubricants, as it reduces friction between moving parts, preventing wear and tear. However, the statement "Religion" is not a valid use of oil and seems to be a mistake or irrelevant option. Therefore, the correct answer is "All of the above" excluding the option "Religion".

6.

The non-polar chemical property of oil makes it a.....?
- A.
  
  Viscous fluid
- B.
  
  Gelatinous liquid
- C.
  
  Inviscid liquid
- D.
  
  Gas
Correct Answer
A. Viscous fluid

Explanation
Oil is a viscous fluid because of its non-polar chemical property. Non-polar molecules do not have positive or negative charges, which means they do not easily interact with other substances. In the case of oil, its non-polar nature allows the molecules to slide past each other with little resistance, resulting in a thick and sticky consistency. This viscosity is what makes oil flow slowly and cling to surfaces, making it a viscous fluid.

If oil does not easily adhere to other substances, thus oil is useful in.....?
- A.
  
  Glass making
- B.
  
  Lubricants
- C.
  
  Fuel
- D.
  
  Heat transfer
Correct Answer
B. Lubricants

Explanation
Oil is useful in lubricants because it does not easily adhere to other substances. This property allows the oil to form a protective layer between moving parts, reducing friction and preventing wear and tear. Lubricants are commonly used in machinery and engines to ensure smooth operation and prolong the lifespan of the equipment.

Oil in fuel is mainly....?
- A.
  
  Carbon
- B.
  
  Nitrogen
- C.
  
  Hydrocarbon
- D.
  
  Hydrogen
Correct Answer
C. Hydrocarbon

Explanation
Oil in fuel is mainly composed of hydrocarbons. Hydrocarbons are organic compounds made up of hydrogen and carbon atoms. Oil is a mixture of various hydrocarbons, ranging from small molecules like methane to large molecules like asphalt. These hydrocarbons are derived from fossilized organic matter, such as plants and animals, that have undergone intense heat and pressure over millions of years. Hydrocarbons are the primary components of oil and give it its energy-rich properties, making it an important source of fuel for various industries and transportation.

Which of the following is one of the oil properties?
- A.
  
  Viscosity
- B.
  
  Density
- C.
  
  Isothermal compressibility
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
All of the options mentioned (viscosity, density, and isothermal compressibility) are indeed oil properties. Viscosity refers to the thickness or resistance to flow of the oil, density refers to the mass per unit volume of the oil, and isothermal compressibility refers to the change in volume of the oil with respect to changes in pressure at a constant temperature. Therefore, all three options are valid oil properties.

..... Is a chemical which allows Oil to mix with water?
- A.
  
  Emulsifier
- B.
  
  Distiller
- C.
  
  Chlorine
- D.
  
  Iodine
Correct Answer
A. Emulsifier

Explanation
An emulsifier is a chemical that allows oil and water to mix together. It works by reducing the surface tension between the two substances, allowing them to form a stable mixture called an emulsion. This is achieved by having one end of the emulsifier molecule attracted to water molecules, while the other end is attracted to oil molecules. As a result, the emulsifier acts as a bridge between oil and water, enabling them to form a homogeneous mixture. Distiller, chlorine, and iodine do not have the same properties as an emulsifier and do not facilitate the mixing of oil and water.
