Question

Give a real-world example of an energy transformation that uses two of the following forms of energy: chemical, mechanical, nuclear, gravitational, radiant, electrical, thermal (heat), and/or sound.

Answer 1

Plants transform radiant energy from the sun into chemical energy during photosynthesis, and car engines convert chemical energy from fuel into mechanical energy. These real-world examples show the transformation of energy from one form to another.

Step-by-step explanation:

Energy transformation occurs when energy changes from one form to another. A real-world example of this is the use of photosynthesis in plants. During photosynthesis, plants convert radiant energy from the sun into chemical energy stored in glucose. This transformation is essential for life on Earth as it is the basis for the food chain.

Another common example involves the use of a car engine. The engine transforms the chemical energy from the fuel (such as gasoline) into mechanical energy that powers the car's movement. The burning gasoline produces heat, which converts water into steam, driving the engine's pistons and producing mechanical energy to turn the wheels.

It is important to note that in these transformations, not all the energy gets converted into the desired form as some of it is always transferred to the environment, often in the form of heat.

Answer 2

Nuclear energy gets converted into heat energy during a detonation and is also used in nuclear power plants where the heat energy form the nuclear energy gets converted into mechanical energy by converting water into steam, rotating the turbines and converting that into electrical energy

Step-by-step explanation:

Or heat engines, such as the internal combustion engine used in cars, or the steam engine. (Heat - Mechanical energy)
