The given table lists some of the fuels along with their calorific values and ignition temperatures. | ||
Fuel | Calorific value (KJ/g) | Ignition temperature\[{{(}^{o}}c)\] |
P | 100 | 5 |
Q | 80 | 50 |
R | 30 | 60 |
S | 20 | 70 |
A) P
B) Q
C) R
D) S
Correct Answer: B
Solution :
There are several factors which are considered while choosing a fuel. A good fuel should have high calorific value and a low ignition temperature. However, the ignition temperature must not be lower than room temperature (so that it does not catch fire at room temperature). Fuel Q is adequate because it has high calorific value and low ignition temperature. The correct answer is B.You need to login to perform this action.
