Correct Answer - Option 3 : CNG pipelines are difficult to get installed
The correct answer is CNG pipelines are difficult to get installed.
Explanation-
CNG is a compressed natural gas.
- It is considered better over diesel/petrol because of the following reasons-
- It burns most efficiently without leaving any unburnt remnant behind.
- It is cheaper than petrol or diesel and less polluting than petrol.
- It cannot be adulterated easily like petrol or diesel.
- Caloric values of CNG and petrol are 50,000 kJ/kg and 45000 kJ/kg respectively. So, CNG is more effective.
- The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its calorific value.
- The calorific value of a fuel is expressed in a unit called kilojoule per kilogram (kJ/kg).
- CNG is used for power generation.
- It is now being used as a fuel for transport vehicles because it is less polluting.
- Compressed natural gas disperse easily when released.
- It produces more heat than petrol as this disperses more easily when released due to high calorific value.
- CNG tanks require more space and are heavy.
Thus, CNG pipelines are difficult to get installed is a major issue in preventing the widespread use of CNG over petrol.
