Question

Give 5 examples of energy transformation.

Answer 1

Hint: Energy exists in many forms. Examples of different forms of energy are mechanical energy, light energy, etc. Although there are many forms of energy these come under two categories. One is the potential energy and another one is kinetic energy. Kinetic energy is the energy that is found in moving objects. Potential energy is a form of energy that is stored potential in a body that can be put to future use.

Complete step-by-step solution:
Energy conservation is the process of converting one form of energy to another form. Energy conversion takes place everywhere and every minute. Whether the energy is transferred or transformed the total form of energy doesn’t change. We can know this from the law of conservation of energy.
Here are some examples of energy transformation.
$\bullet$ Electric motors are used in different appliances like fans and refrigerators, etc. In these electric motors, electrical energy is converted into kinetic energy.
$\bullet$ Cells- They are used in many electronic gadgets. In these cells, chemical energy is present which is converted into electrical energy.
$\bullet$ Solar water heaters are used to heat the water using sunlight. This sunlight is a form of light energy that is converted into heat energy.
$\bullet$ The toaster used in our kitchens converts electrical energy into thermal energy.
$\bullet$ Our human bodies convert chemical energy through our foods into mechanical energy

Note: All these energy conversions are governed by thermodynamics. Thermodynamics has laws that govern these energy conversions. In which the first law is the law of conservation of energy. This law of conservation of energy can be stated that energy can neither be created nor destroyed. But it can be transformed from one form to the other. This is the main law that governs these energy transformations.
