What is the primary function of a boiler in a thermal power plant?
A Fuel combustion
B Electricity generation
C Water storage
D Heat generation
The primary function of a boiler in a thermal power plant is to generate heat. The boiler burns fuel, typically coal or natural gas, to heat water, converting it into steam. This steam drives turbines to generate electricity.
In hydroelectric power plants, what happens to water before it enters the turbine?
A Frozen
B Pressurized
C Stored
D Heated
In hydroelectric plants, water is stored in a reservoir and then directed through large pipes known as penstocks. The pressure created by the height difference causes the water to flow rapidly, which spins the turbine to generate power.
Which type of energy is converted into electricity in a nuclear power plant?
A Electrical
B Kinetic
C Nuclear
D Chemical
Nuclear power plants convert nuclear energy into electrical energy. The process of nuclear fission splits uranium atoms, releasing vast amounts of heat, which is used to create steam that drives turbines connected to generators.
Which is the most common fuel used in thermal power plants?
A Coal
B Natural gas
C Biomass
D Uranium
Coal is the most commonly used fuel in thermal power plants. When burned, coal generates heat that is used to convert water into steam. The steam powers turbines that drive generators to produce electricity.
What is the key component that converts mechanical energy into electrical energy in hydroelectric power plants?
A Battery
B Turbine
C Generator
D Boiler
In hydroelectric power plants, the turbine is the key component that converts the mechanical energy of flowing water into electrical energy. The turbine spins when water flows over it, driving a generator that produces electricity.
What is the most important factor in determining the output of a hydroelectric power plant?
A Fuel type
B Wind speed
C Water flow
D Temperature
The output of a hydroelectric power plant depends on the flow rate of water. The greater the volume and speed of the water, the more energy can be generated. Water flow is directly related to the power generation capacity.
In a nuclear power plant, what is used to control the rate of the nuclear reaction?
A Control rods
B Turbines
C Boilers
D Generators
Control rods are used in nuclear power plants to control the rate of the nuclear reaction. These rods are made of materials that absorb neutrons, thereby reducing the number of neutrons available to continue the fission process.
Which component of a nuclear power plant generates the steam required to drive turbines?
A Generator
B Heat exchanger
C Control rods
D Reactor
In a nuclear power plant, the reactor generates heat through nuclear fission. This heat is used to convert water into steam. The steam then drives turbines that are connected to generators to produce electricity.
Which power generation method relies on the movement of water in rivers or dams?
A Solar
B Hydroelectric
C Tidal
D Wind
Hydroelectric power plants rely on the movement of water in rivers or dams to generate electricity. The potential energy of water stored at height is released to flow through turbines, generating mechanical energy that is converted into electricity.
Which fuel type is used in both coal and natural gas power plants to generate electricity?
A Uranium
B Geothermal
C Fossil fuels
D Biomass
Both coal and natural gas power plants use fossil fuels to generate electricity. These fuels are burned to produce heat, which generates steam. The steam drives turbines connected to generators that produce electrical energy.
What is the main difference between thermal and nuclear power plants?
A Emissions
B Fuel type
C Generator type
D Power transmission
The main difference between thermal and nuclear power plants is the fuel type used. Thermal plants typically use fossil fuels like coal, while nuclear power plants use uranium for nuclear fission to generate heat and electricity.
In which type of power plant is steam generated from geothermal heat?
A Biomass
B Solar
C Wind
D Geothermal
Geothermal power plants generate steam by harnessing heat from beneath the Earth’s surface. This steam is used to drive turbines, which generate electricity. Geothermal energy is sustainable and renewable.
Which component of a thermal power plant converts heat into mechanical energy?
A Turbine
B Transformer
C Boiler
D Generator
In thermal power plants, the turbine converts the thermal energy (heat) into mechanical energy. Steam from the boiler drives the turbine, which is connected to a generator that produces electrical energy.
Which of these methods is used to store excess electricity in a power plant?
A Wind storage
B Heat storage
C Battery storage
D Coal storage
Battery storage systems are often used to store excess electricity produced during times of low demand. This stored electricity can then be used during periods of high demand, improving grid stability and ensuring reliable power supply.
Which is a major advantage of using nuclear power for electricity generation?
A Safety concerns
B Low emissions
C High cost
D Limited fuel supply
One of the major advantages of nuclear power is that it produces low emissions. Unlike fossil fuel plants, nuclear power plants do not emit greenhouse gases or air pollutants, making them a cleaner alternative for large-scale electricity generation.
