- Q1
How can the function of the turbine in a geothermal power plant be explained in terms of energy transformation? The turbine____________.
converts the mechanical energy to chemical energy to thermal energy
converts thermal energy to mechanical energy to electrical energy
cools the steam before it reaches the condensing tower
turns the hot water into steam for further use
60s - Q2
Why is it important for the steam in a geothermal plant to be condensed before being reinjected into the ground? To_____________________.
maintain the pressure needed to drive the turbine and continue to function
recycle the water and ensure the continuous use of geothermal energy without depleting resources
cool down the hot rocks underground and prevent the magma to heat the rocks
prevent the steam from becoming too hot and causing environmental damage
30s - Q3
How would a decrease in the temperature of the hot rock/soil below the geothermal plant affect the entire energy production process? It would _______________.
increase the amount of steam generated
make the steam too hot, causing damage to the turbine
have no effect on energy production
reduce the amount of steam generated
30s - Q4
What will be the efficiency of a geothermal powerplant might change if the condensing tower were removed from the system.
The plant would generate more electricity because there would be no need to cool the steam
The steam would not cool down, and the plant would be unable to reuse the water
The plant’s efficiency would remain the same because cooling the steam is unnecessary for power generation
The steam would be cooler, increasing the amount of energy produced by the generator
30s - Q5
In a geothermal power plant, which part is responsible for maintaining the supply of geothermal heat for energy production?
turbine
injection well
magma
generator
