10th Unit 3 Module 1 Quiz

Which type of energy is stored in food, gasoline, or batteries?

• Kinetic energy

• Chemical energy

• Thermal energy

• Electrical energy

Answer explanation

Chemical energy is the type of energy stored in food, gasoline, and batteries. It is released during chemical reactions, such as digestion or combustion, making it the correct choice.

Which of the following is a form of energy associated with an object’s motion?

• Thermal energy

• Mechanical energy

• Electrical energy

• Nuclear energy

Answer explanation

Mechanical energy is the form of energy associated with an object's motion. It includes both kinetic energy (energy of motion) and potential energy (stored energy due to position).

Which energy conversion happens in a hydroelectric power plant?

• Kinetic energy to electrical energy

• Chemical energy to electrical energy

• Thermal energy to kinetic energy

• Gravitational potential energy to chemical energy

Answer explanation

In a hydroelectric power plant, water flows from a height, converting gravitational potential energy into kinetic energy as it moves. This kinetic energy is then transformed into electrical energy using turbines and generators.

What is the primary energy conversion that happens in a nuclear power plant?

• Nuclear energy to electrical energy

• Electrical energy to mechanical energy

• Chemical energy to thermal energy

• Kinetic energy to nuclear energy

Answer explanation

In a nuclear power plant, nuclear energy is released through fission reactions, which is then converted into thermal energy. This thermal energy is used to produce steam that drives turbines, ultimately generating electrical energy.

Which of the following is a renewable energy source?

• Coal

• Wind

• Natural gas

• Oil

Answer explanation

Wind is a renewable energy source because it is generated from natural processes that are continuously replenished. In contrast, coal, natural gas, and oil are fossil fuels that deplete over time.

In a lightbulb, what form of energy is primarily converted to light?

• Electrical energy to light energy

• Thermal energy to chemical energy

• Chemical energy to electrical energy

• Kinetic energy to light energy

Answer explanation

In a lightbulb, electrical energy is converted into light energy through the process of incandescence or fluorescence, making 'Electrical energy to light energy' the correct choice.

What form of energy is stored in a battery?

• Kinetic energy

• Electrical energy

• Chemical energy

• Gravitational energy

Answer explanation

A battery stores energy in the form of chemical energy, which is released during chemical reactions to produce electrical energy when the battery is used.

How does solar energy work in a solar panel?

• It converts light energy directly into electrical energy

• It converts thermal energy into light energy

• It stores chemical energy in a battery

• It converts electrical energy into mechanical energy

Answer explanation

Solar panels work by converting light energy from the sun directly into electrical energy through the photovoltaic effect, making the first answer choice correct.

What type of energy does a moving car primarily have?

• Chemical energy

• Thermal energy

• Kinetic energy

• Electrical energy

Answer explanation

A moving car primarily has kinetic energy, which is the energy of motion. As the car moves, it possesses this energy due to its speed and mass, making kinetic energy the correct choice.

What energy conversion happens in a wind turbine?

• Kinetic energy to electrical energy

• Electrical energy to kinetic energy

• Thermal energy to mechanical energy

• Gravitational energy to kinetic energy

Answer explanation

In a wind turbine, the kinetic energy of the wind is converted into electrical energy. The turbine blades capture the wind's kinetic energy, which is then transformed into electricity through a generator.
