Which of the following most accurately explains how geothermal energy is produced and utilized in these applications? Geothermal energy uses the natural insulating power of Earth to create temperature differentials that are used to heat buildings in the winter and cool them in the summer.
Which of the following is required to convert geothermal energy into electricity?
Geothermal power plant in the Imperial Valley, California. A geothermal resource requires fluid, heat and permeability in order to generate electricity: Fluid—Sufficient fluid must exist naturally or be pumped into the reservoir.
Which of the following best explains energy transformation in hydrogen fuel cells?
What best explains energy transformation in hydrogen fuel cells? Hydrogen reacts with oxygen to produce water, which releases energy.
Which of the following best describes a potential advantage of using geothermal energy instead of solar farms?
Which of the following best describes a potential advantage of using geothermal energy instead of solar farms for power generation? … Geothermal energy can be harnessed without destroying large tracts of habitat, whereas solar farms require large amounts of space.
How many kilowatt hours kWh per year does refrigerator a use 6kwh?
A fridge will use anywhere from 100 to 400 watts depending on size, a large fridge will use about 180 watts or 1575 kWh annually.
What are the forms of geothermal energy?
There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.
Is hydrogen fuel liquid or gas?
Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 degrees Fahrenheit (minus 253 degrees Celsius).
Why hydrogen is not used as a fuel?
Hydrogen has the highest calorific value so it can be considered as the best fuel but it is highly inflammable so it is diificult to store, transport and handle so it is used as a fuel only where it is absolutely necessary.
What two waste products are produced by hydrogen fuel cells?
If pure hydrogen is used as a fuel, fuel cells emit only heat and water as byproducts. 1 Also called a gas battery. Green Chemistry – designing chemical products and processes to reduce or eliminate the use or generation of hazardous materials.
Which of the following best describes the use of hydrogen fuel negatively impacts the environment?
Which of the following best describes how the use of hydrogen fuel negatively impacts the environment? The energy needed to produce the hydrogen fuel may come from fossil fuels, whose use contributes to ocean acidification and global climate change.
Why is the use of natural gas increasing quizlet?
Natural gas use is increasing in 3 main areas; electricity generation, transportation and commercial cooling. Fossil fuels the energy comes from chemical bonds but with nuclear energy the energy comes from changes in the atoms.
Which of the following best describes an environmental problem that is often linked to the process of fracking? Fracking operations require large tracts of land, which degrades habitat and harms wildlife. Fracking can increase stream flow and water volume, disrupting fish migration pathways.
