What is good fuel economy?

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You’ll often see it referred to as ‘fuel economy’.

What are the qualities of an ideal source of energy give the names of two energy sources that you would consider to be exhaustible?

Coal and petroleum are the two energy sources that are considered to be exhaustible. They are non-renewable sources of energy and are present in a limited amount in the earth. Once exhausted, they will not be available to us again.

Why is there a need to harness non conventional sources of energy?

Answer. The two main reasons to harness non-conventional sources of energy are: … As, fossil fuels like coal, petroleum, are present in a limited amount which and are likely to finish one day so the need for alternative sources of energy is essential. (ii) Use of conventional sources of energy (coal, petroleum etc.)

What are the two main sources of energy in the body?

The food you eat supplies many types of macronutrients — carbohydrates, fats and proteins — which deliver the energy (or calories) your body needs to function.

What gives energy to humans?

This energy comes from the food we eat. … Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.

What is a good source of energy *?

A good source of energy fulfils the following criteria: It produces a lot of heat per unit mass. It does a huge amount of work per unit mass. It is easily accessible. It is easy to store and transport.

What are the 3 types of fuel?

Fossil fuels principally consist of carbon and hydrogen bonds. There are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas. Coal is a solid fossil fuel formed over millions of years by decay of land vegetation.

What are the 3 sources of energy for the body?

Humans obtain energy from three classes of fuel molecules: carbohydrates, lipids, and proteins. The potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms.

What are the qualities of an ideal fuel?

An ideal fuel should have the following properties:It should possess high calorific value.It should have proper ignition temperature. … It should not produce poisonous products during combustion. … It should have moderate rate of combustion.More items…

What is a natural source of energy for the body?

Bananas. When you eat a banana, you provide energy to your body by supplying it with carbs, vitamin B6, and potassium, all of which can help you feel more energized.

What is the good fuel?

A fuel is considered good or desirable when it has a low ignition temperature and generates a significant amount of heat. It reflects it high in its calorific value. Ideal fuels should be easy to store, leaving behind ash after they are burned and quickly combust.

What are the qualities of ideal source of energy?

An ideal source of energy should possess the following characteristics. (a) It should be capable of giving an adequate amount of useful energy. (b) It should be convenient to transport, store and use. (c) It should be economical.
