What is the main challenge associated with the commercialization of fuel cells?
-
High cost of production
-
Lack of hydrogen infrastructure
-
Low efficiency
-
Limited fuel availability
A
Correct answer
Explanation
The high cost of production and the lack of a well-developed hydrogen infrastructure are major challenges hindering the widespread commercialization of fuel cells.
What is the primary challenge associated with the use of hydrogen as a fuel in fuel cells?
-
High cost of production
-
Lack of hydrogen infrastructure
-
Low energy density
-
Toxicity
B
Correct answer
Explanation

What is the primary source of energy that drives volcanic eruptions?
-
Solar radiation
-
Geothermal heat
-
Wind power
-
Hydroelectric power
B
Correct answer
Explanation
Volcanic eruptions are primarily driven by the heat generated within the Earth's mantle, which is the layer beneath the crust. This heat causes rocks to melt and form magma, which rises to the surface and erupts.
