Question

Hydrogen could well be a fuel for the future. Which of the following statements is true about the potential use of hydrogen as a fuel?
A.Easily liquefiable
B.Produces lots of greenhouse gas on combustion
C.Explosive when mixed with air
D.All of the above

Answer 1

Hint: We have to know hydrogen is present in the first group and first period in the periodic table. We have to know that hydrogen is the lightest element and first element in the periodic table. Because hydrogen weighs less when compared to air, it increases in the atmosphere, and so, it is rarely present in pure form.

Complete answer:
We have to know that hydrogen fuel is a zero carbon fuel ignited with oxygen. It may very well be utilized in power devices or inner burning motors. It has started to be utilized in business power device vehicles, like traveler vehicles, and has been utilized in energy unit transports for a long time. It is likewise utilized as a fuel for shuttle drive. The energy delivered empowers hydrogen to go about as a fuel. In an electrochemical cell, that energy can be utilized with moderately high effectiveness. On the off chance that it is utilized essentially for heat, the typical thermodynamics limits on the warm productivity apply.
Fuel cells present the most attractive decision for energy change from hydrogen straightforwardly towards power, because of their high productivity, low commotion, and predetermined number of moving parts. Energy components are of interest for both fixed and generated mobile power from hydrogen. Fuel cells are frequently considered as a component of a vehicle drive framework.
Utilizing an energy component to control an electric powertrain including a battery and an electric engine is a few times more productive than utilizing a burning motor, though a portion of this advantage is identified with the electric powertrain. This implies that a lot more noteworthy mileage is accessible utilizing hydrogen as a fuel cell, contrasted with that of hydrogen burning motor.

The statement is true about the potential utilization of hydrogen as a fuel as it is an explosion when mixed with air. Option (C) is correct.

Note:
We have to know that there are some advantages of hydrogen as transportation fuel as it is high energy yield, high diffusivity, most versatile fuel, the major oxidation product is water vapor, and hydrogen fuel is produced from several primary sources of energy and has wide flammability range. Some of the disadvantages of hydrogen as transportation fuel is hydrogen fuel are expensive, low ignition energy and low density.
