Option (J) and Option (W) are the correct options.
(J) Heavy Motor vehicles run on Diesel is the correct option.
- Diesel and petrol have almost the same calorific value at room temperature. But the density of diesel is greater than petrol thus giving 15% more energy per unit volume on combustion.
- Diesel engines produce much more torque (you can say the pushing force) than petrol ones, which is more required for heavy vehicles.
- Diesel engines are more fuel efficient than petrol engines.
- Diesel is oil whereas petrol is a spirit. Diesel is less volatile as well as less inflammable. Thus safer to carry in large quantities.
(S) In India, Oil is Found only in the river basins of Godavari and Krishna is an incorrect option is an incorrect statement.
There are many oil fields located in different places in India.
- The major oilfields in northeast India are those of the Brahmaputra valley in Assam and its neighboring areas including Arunachal Pradesh, Nagaland, Meghalaya, Tripura, Manipur, and Mizoram.
- On-Shore Oil Fields of Western India is located at Ankleshwar, Khambhat or Lunej field, Ahmedabad and Kalol field, Mumbai High, Bassein, etc.
(T)Petroleum Gas is heavier than water is an incorrect statement.
- There is no gas heavier than water under standard conditions.
(W) The porous rocks over petroleum are made of sand and clay particles is also a correct statement.
- The oil is found always by water and often by natural gas; all are confined in a porous and permeable reservoir rock, which is usually composed of sedimentary rock.
- The sedimentary rocks include sandstones, arkoses, fissured limestones, and dolomites.
- Sandstone is made up of sand and clay.
Hence, Option (J) and Option (W) are the correct options.
