Explanation

The fabrication step where proper interconnection of circuit elements is made is called Metallization.

Metallization is often accomplished with a vacuum deposition technique
***

Explanation

Some materials hold their electrons very tightly. Electrons do not move through them very well. These things are called Insulators.

In some materials such as glass, rubber, wood and most plastics, the electrons are held quite tightly.

These materials are called insulators.

Explanation

The capacitance between two parallel charges sheets is dependent upon surface area and distance between the plates.

Capacitance of a parallel plate capacitor depends on the dielectric constant of the medium between the plates, area of each plate and distance between the plates.

Explanation

• If the pH value is greater than 7, the solution is basic (also known as alkaline).
• This means that the concentration of hydroxide ions (OH-) is higher than the concentration of hydrogen ions (H+).

Key Points:

• pH < 7: Acidic
• pH = 7: Neutral
• pH > 7: Basic (or alkaline)

Explanation

The atomic number of neon is 10.

This means neon has 10 protons in its nucleus.

Explanation

Sulphur is a non-metal element.

It does not exhibit the characteristics of metals, such as conductivity, malleability, and ductility.

Instead, it is brittle and non-conductive.

Explanation

Ammonia (NH3) is not a fraction of crude oil.

Crude oil is a mixture of various hydrocarbons, which are separated into different fractions based on their boiling points and properties.

The main fractions of crude oil are:

• Refinery gas
• Liquefied petroleum gas (LPG)
• Naphtha
• Gasoline
• Kerosene
• Diesel fuel
• Fuel oil
• Lubricating oils
• Paraffin wax
• Petroleum coke (also known as petcoke)

Explanation

Kerosene oil is used as jet fuel, commonly known as Jet-A or Jet-A1.

It has a high energy density and good combustion properties suitable for aircraft engines.

Explanation

Harvesting is the most important step in the preparation of sugar from sugarcane or sugar beets.

Sugarcane is typically harvested by hand or by machine, and sugar beets are harvested by machine.

The quality of the harvest affects the quality of the sugar produced.

Explanation

Abrasives are substances that wear away or remove material through friction or rubbing.

Examples of abrasives include:

Water insoluble minerals like:

• Silica (sand)
• Alumina (aluminum oxide)
• Calcium carbonate (limestone)
• Diamond
