Question

Energy can be transferred from one form to another. We use many energy
converters in our daily life. Observe carefully to find these energy converters in your
home. Make a list of any 10 converters including their names along with their energy
chains.

Answer 1

Answer:

Energy is the fundamental need of our everyday life. So much so, that the quality of life and even its sustenance, is dependent on the availability of energy. Hence, it is imperative for us to have a conceptual understanding of the various sources of energy, the conversion of energy from one form to another and the implications of these conversions.

You must have heard that heard that Energy conversion from one form to another is a well-known phenomenon. The Law of conservation of energy even tells us that the only thing that takes place with energy is the transformation from one form to another. This means that we can convert electrical energy into heat energy and light energy, solar energy can be converted to chemical energy, potential energy can be converted into kinetic energy, Gravitational potential energy can be converted into kinetic energy etc.

Energy Conversion is defined as the process where there is a change in energy from one form to another such as the conversion of nuclear energy into heat energy, the conversion of light energy into heat, thermal energy into work etc.

Types of Energy Conversions

There are various types of energy all around us and these energy sources can be converted from one form to another as explained below:

•Light energy can be converted to heat energy.

•Electrical energy can be converted to mechanical energy, light energy, heat energy, etc.

•Chemical energy can be converted to electrical energy.

•Thermal energy can be converted to heat energy.

•Mechanical energy can be converted to electrical energy, potential energy, etc.

•Nuclear energy can be converted to light energy and heat energy.

•The Solar energy can be converted to heat energy, chemical energy, and electrical energy.

•The Gravitational potential energy can be converted to kinetic energy.

Answer 2

Answer:

Energy can be transferred from one form to another.

• The energy transformation is also called energy conversion. It is the process of changing one form of energy into another form.
• Whether the energy is transferred or transformed the total amount of energy doesn't change.
• The energy can neither be created nor be destroyed. But it can convert one form into another form.
• There are several forms of energy like electrical energy, chemical energy, thermal energy, kinetic energy, potential energy, nuclear energy, electrochemical energy, and mechanical energy.

Some energy converters we use in the home are as follows,

• Battery powered to torchlight, where the transfer of chemical energy to electrical energy takes place.
• The electric generator here is the transfer of mechanical energy to electrical energy.
• In an electric lamp, the transfer of electric energy to light energy takes place.
• An electric heater is the transfer of electric energy to heat.
• Microphone here, the transfer of sound energy to electric energy.
• In a light bulb electric energy changes to thermal and light energy.
• During photosynthesis, light energy is converted into chemical energy.
• In the fan, the electric energy is converted into kinetic energy.
• In iron, the electric energy is converted into heat.
• In radio, the electric energy is converted into kinetic energy, and sound energy.
