..... Is a chemical which allows Oil to mix with water?

Emulsifier
Distiller
Chlorine
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.

Oil can be derived from which of the following?

Water
Atmosphere
Alcohol
Hydrocarbons

Correct Answer

A. 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?

Organic oil
Inorganic oil
Mineral oil
Natural oil

Correct Answer

A. 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 in fuel is mainly....?

Carbon
Nitrogen
Hydrocarbon
Hydrogen

Correct Answer

A. 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.

If oil does not easily adhere to other substances, thus oil is useful in.....?

Glass making
Lubricants
Fuel
Heat transfer

Correct Answer

A. 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.

The hydrophobic nature of oil means?

It is water loving
It is fat loving
It is water-repellent
It is bibulous

Correct Answer

A. 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.

The non-polar chemical property of oil makes it a.....?

Viscous fluid
Gelatinous liquid
Inviscid liquid
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.

Oil is a viscous liquid at..... Temperature

Ambient
High
Low
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.

Oil is used in......?

Heat transfer
Lubricants
Religion
All of the above

Correct Answer

A. 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".
