Question

Which is one disadvantage of using gas hydrates?

A) they are scarce

B) they rapidly break down at surface temperatures and pressures

C) They are expensive to mine

D) they are located in very cold regions

Answer 1

Your answer would be B.They rapidly break down at surface temperatures and pressures.

Answer 2

Option (B)

Step-by-step explanation:

Gas hydrates are the solid crystals that are made of gas and water. This gas hydrates on burning emits methane gas.

They are formed in the region of high pressure and low temperature. Generally, they are found to be trapped in the permafrost layers in the Arctic area. In order to obtain these gas hydrates, huge amount of money is required for extraction purpose.

These gas hydrates have certain drawbacks that they are stable only under high pressure and low-temperature condition, but if it reaches to a region of low pressure and high temperature then the molecules within it get segregate and methane is released that reacts with the ocean water and contaminates, thereby leading to the increase in global temperature.

Hence, the correct answer is option (B).
