Question

Which among the following is not a characteristic of an ideal fuel?

• A. High ignition temperature
• B. High calorific value
• C. Less smoke
• D. Easy to transport

Answer 1

The correct option is A High ignition temperature

Ignition temperature is the minimum temperature at which a substance catches fire. An ideal fuel should have moderate ignition temperature. High ignition temperature will make it tough to be ignited. An ideal fuel should have high calorific value i.e., it should produce more heat in less quantity of fuel. Less smoke while undergoing combustion and easy tranportability are also characteristics of an ideal fuel.
