Explanation

CNG (Compressed Natural Gas) is primarily composed of methane.

When comparing the burning efficiency of CNG to other gases

It is generally understood that CNG burns less efficiently than Propane

Propane has a higher energy content per unit volume compared to methane, meaning it can produce more energy when burned.

Explanation

In Java, a class cannot inherit from more than one superclass to avoid ambiguity.

However, it does support single inheritance, multilevel inheritance, and hierarchical inheritance.

To achieve some aspects of multiple inheritance, Java uses interfaces, allowing a class to implement multiple interfaces.

Explanation

Butter is primarily made from fat, particularly milk fat, and is much richer in fat compared to bananas and milk.

Explanation

Oxy-acetylene welding is a very common welding process.

Gases used in welding and cutting processes include:

• shielding gases such as carbon dioxide, argon, helium, etc.
• fuel gases such as acetylene, propane, butane, etc.

oxygen, used with fuel gases and also in small amounts in some shielding gas mixtures

Explanation

The part of the ear that primarily belongs to hearing is the Cochlea.

The cochlea is responsible for converting sound vibrations into neural signals that the brain interprets as sound.

Explanation

Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium.

Explanation

Joseph Priestley invented soda water in 1767 by infusing water with carbon dioxide.

His method laid the foundation for carbonated beverages.

Explanation

Ozone (O3) is a gas found in the stratosphere.

A stratosphere layer of the atmosphere that extends from about 12 to 50 kilometers (7.5 to 31 miles) above the Earth's surface.

The ozone layer, also known as the ozonosphere.

Explanation

Thermal cracking is a process in which high temperatures are used to break down large hydrocarbon molecules into smaller, more useful molecules.

Such as gasoline and diesel.

This process is widely used in the petroleum industry.

Explanation

The volume of an atom is typically calculated using the atomic radius and the formula for the volume of a sphere (V = (4/3)πr³), where r is the atomic radius.

The atomic radius is the distance from the nucleus to the outermost electron orbital.
