(a)
Interpretation:
Five fuels have to be listed and two properties that these fossil fuels share have to be given.
Concept introduction:
Non-Conventional energy source: The resources which occur by natural process and can be recyclable or replaced. They will be much useful to human beings. The use of non-conventional energy sources contribute less pollution in the atmosphere and this is the reason for their increase use.
Conventional energy source: The resources which are once used and which cannot be available again within a given amount of time. Gasoline, coal, diesel, plastic etc are examples for conventional energy resources. Fossil fuels are considered to be conventional energy source.
(a)
Explanation of Solution
Fuels can be defined as the substances which are able to react with other substances and releases energy which can be used for work. The major crisis faces by human today is energy crisis. Different energy sources are available and these can be classified as renewable energy resource and non-renewable energy resource.
The common fuels are given below:
- Coal.
- Oil.
- Natural gas.
- Propane.
- Biodiesel
The common properties of fuels are they produce large amount of heat, high caloric value and does not leave behind any undesirable substances.
(b)
Interpretation:
Fossil fuels or those derived from the listed fuels has to be identified from the list.

(b)
Explanation of Solution
The common fuels are given below:
- Coal.
- Oil.
- Natural gas.
- Propane.
- Biodiesel
The fossil fuel is an example for conventional energy source and coal is an example for fossil fuel. They are non-renewable and make environmental pollution to a certain extent.
(c)
Interpretation:
The renewable fuels have to be identified from the list.

Explanation of Solution
The common fuels are given below:
- Coal.
- Oil.
- Natural gas.
- Propane.
- Biodiesel
Of the given fuels, biodiesel is only fuel which can be renewable. The sustainability and the lower amount of green-house gas emissions made these types of fuels popular.
Natural gas, propane and other fossil fuels are examples for non-renewable.
