FA24 Unit Six Review

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

Why does sand heat up and cool down faster than water?

Back

Sand has a lower specific heat capacity than water, meaning it requires less energy to change its temperature.

Front

What is the significance of a high specific heat capacity?

Back

A substance with a high specific heat capacity can absorb and store more heat energy, leading to smaller temperature changes.

Front

What is hydroelectric power?

Back

Hydroelectric power is electricity produced by harnessing the energy of flowing water.

Front

What is a downside of hydroelectric energy?

Back

A possible downside is the high startup cost associated with building hydroelectric plants.

Front

What percentage of energy used in the U.S. comes from renewable sources?

Back

Approximately 10% of energy used in the U.S. comes from renewable energy sources.

Front

What is the primary source of energy for hydroelectric power?

Back

The primary source of energy for hydroelectric power is flowing water.

Front

How does specific heat capacity affect climate?

Back

Areas with large bodies of water tend to have milder climates due to the high specific heat capacity of water, which stabilizes temperature fluctuations.

Front

What is the relationship between specific heat capacity and temperature stability?

Back

Substances with high specific heat capacity tend to maintain a more stable temperature compared to those with low specific heat capacity.

Front

What are some examples of renewable energy sources?

Back

Examples of renewable energy sources include solar, wind, hydroelectric, and geothermal energy.
