How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is the energy transformation in a hydroelectric dam?

Answer: Potential to kinetic to electrical energy. Stored water energy converts to mechanical then electrical.

Flashcard 2: Which fossil fuel is formed from marine organisms?

Answer: Petroleum. Ancient marine plankton formed oil under sediment layers.

Flashcard 3: Identify a renewable energy source that can also provide heating.

Answer: Geothermal energy. Underground heat provides both electricity and direct heating.

Flashcard 4: Name the process of generating electricity from moving water.

Answer: Hydroelectric generation. Water flow through dams spins turbines for electricity.

Flashcard 5: Which type of coal has the highest carbon content?

Answer: Anthracite. Highest grade coal with 86-97% carbon content.

Flashcard 6: Which renewable energy source uses dammed water to generate electricity?

Answer: Hydroelectric power. Water flow through turbines generates electricity.

Flashcard 7: Identify the type of biofuel made from corn or sugarcane.

Answer: Ethanol. Alcohol fuel produced by fermenting plant sugars.

Flashcard 8: What is the main use of uranium in the energy sector?

Answer: Nuclear power generation. Uranium-235 undergoes fission to produce heat for power plants.

Flashcard 9: What is the primary challenge of using solar energy?

Answer: Intermittent availability. Solar panels need sunlight and don't work at night.

Flashcard 10: Identify the term for the conversion of organic material into fuel.

Answer: Biomass conversion. Transforms organic matter into usable energy forms.

Flashcard 11: Which fuel type is primarily used in internal combustion engines?

Answer: Petroleum. Gasoline and diesel power most vehicle engines.

Flashcard 12: Which fossil fuel is often used as a feedstock in chemical production?

Answer: Natural gas. Natural gas is converted into plastics and fertilizers.

Flashcard 13: What is the energy conversion in wind turbines?

Answer: Kinetic to electrical energy. Wind spins turbine blades to generate electrical power.

Flashcard 14: Which renewable energy source uses photovoltaic cells?

Answer: Solar energy. Photovoltaic cells convert sunlight directly into electricity.

Flashcard 15: What is the main disadvantage of using coal as a fuel?

Answer: High carbon emissions. Coal releases the most $CO_2$ per unit energy.

Flashcard 16: Which renewable energy source is dependent on weather conditions?

Answer: Solar energy. Solar output varies with clouds, seasons, and day/night.

Flashcard 17: What is one advantage of using wind energy?

Answer: Low emissions. Wind power produces minimal greenhouse gas emissions.

Flashcard 18: Identify the fossil fuel that is solid at room temperature.

Answer: Coal. Coal exists as solid chunks at normal temperatures.

Flashcard 19: What is the primary use of petroleum?

Answer: Transportation fuels. Refined into gasoline, diesel, and jet fuel.

Flashcard 20: What is the main environmental impact of using coal?

Answer: Air pollution. Coal burning releases particulates and toxic gases.

Flashcard 21: Identify the fossil fuel that is a liquid at room temperature.

Answer: Petroleum. Crude oil remains liquid at standard temperature and pressure.

Flashcard 22: Which type of coal has the highest carbon content?

Answer: Anthracite. Highest grade coal with 86-97% carbon content.

Flashcard 23: Identify the fuel type that produces the least carbon emissions.

Answer: Nuclear energy. Nuclear fission produces no direct carbon emissions.

Flashcard 24: What is the main use of coal in industrial processes?

Answer: Steel production. Coal provides carbon for reducing iron ore to steel.

Flashcard 25: Name a renewable energy source that relies on wind turbines.

Answer: Wind energy. Turbines capture kinetic energy from moving air masses.

Flashcard 26: What is a common use of natural gas besides energy generation?

Answer: Heating. Natural gas burns cleanly for residential and commercial heat.

Flashcard 27: Name the process of generating electricity from moving water.

Answer: Hydroelectric generation. Water flow through dams spins turbines for electricity.

Flashcard 28: Identify the primary greenhouse gas emitted by burning fossil fuels.

Answer: Carbon dioxide. Fossil fuel combustion releases stored carbon as $CO_2$.

Flashcard 29: Identify one advantage of using geothermal energy.

Answer: Sustainable and reliable. Geothermal provides constant, weather-independent energy.

Flashcard 30: Name the process of splitting atomic nuclei to release energy.

Answer: Nuclear fission. Heavy nuclei split into lighter fragments, releasing energy.
