Question

Write any four characteristics of an ideal fuel.

Answer 1

Hint: To define the characteristics of an ideal fuel, we can discuss the points like calorific value, combustion rate, and the products, ignition temperature, its quality, and cost. On the basis of mentioned points, we can characterize an ideal fuel.

Complete step by step solution:
-First, let us know about the fuel. Suppose, when we burn any substance, then on combustion, there is production of some amount of energy; that energy is termed as fuel. Some examples are biogas, fossil fuels etc.
-As we know, the fuels are differentiated mainly on the basis of their usage, and the calorific value. If we define the calorific value, it is the amount of energy produced by one kg of fuel on combustion.

Now, we will discuss the characteristics of an ideal fuel.
i) The first is that it should depict a high calorific value.
ii) The second is the ignition temperature shown by fuel should neither be too low or nor too high, meaning it should have proper ignition temperature.
iii) We can say that there should not be production of poisonous substances, meaning no cause for pollution.
iv) The most important is no adverse impact on the environment, easily available, and cheap in cost.
v) Next, we can say the combustion rate must be moderate.
vi) In the last we can conclude that the fuel must possess all the mentioned properties to be an ideal fuel.

Note: Don’t be confused between the calorific value, and ignition temperature. We have already discussed the calorific value. The ignition temperature is that temperature when it ignites without any external source like flame, or spark in the normal atmosphere.
