Question

What energy transformation happening when starting a car

Answer 1

Answer:

Explanation:

We're starting a car. We have the fuel in the engine, and when the engine starts, that fuel is converted into power to move the car. The fuel is made of chemicals, right? Propane, gasoline, so on. What kind of energy comes from chemicals? Chemical energy, right?

That fuel is chemical energy, and the energy to move the car must be kinetic/mechanical energy. However, that's not the only source of mechanical energy.

There's another source of mechanical energy here as well: we have an electric battery. What kind of energy is found in a battery? The battery has electricity, and so it has electrical energy. Some of that electrical energy turns into mechanical energy when the car starts up.

But the engine heats up as well, right? There's one more energy that the electrical energy and chemical energy produce here: thermal energy. That's the source of the heat.

I hope this makes sense for you. Have a wonderful day!
