b. Liquefied form of methane under natural gas deposits
c. Liquefied form of methane within rock sediments
d. None of the above
ANSWER: Crystalline form of methane and water
- In chemistry, a hydrate is a substance that contains water in its constituent elements.
- Gas hydrates are crystalline form of methane and water.
- They are envisaged as a viable major energy resource for future.
- Methane hydrate is a mixture of natural gas and water that becomes a solid in cold, high-pressure conditions in deep sea-beds (where the temperature falls to 2 degrees centigrade).
- It is also found in onshore deposits in the permafrost of northern Canada and Russia. Heating the deposits or lowering the pressure (the technique used by Japan Oil Gas and Metals National Corporation) will release gas from the solid. One litre of solid hydrate releases around 165 litres of gas.
