Answer

Explanation:

Step1: Choose an example system

Let's choose a car as the system.

Step2: Analyze energy - entry

Energy enters the car as chemical energy in gasoline. When the gasoline is pumped into the fuel tank, this chemical - energy source is added to the system.

Step3: Analyze energy - transformation

In the engine, the chemical energy of gasoline is converted into thermal energy through combustion. Then, the thermal energy is converted into mechanical energy to move the car. Some of the energy is also converted into electrical energy to power the car's electrical systems (lights, radio, etc.) through the alternator.

Step4: Analyze energy - exit

Energy leaves the car in several forms. Exhaust gases carry away thermal energy. Friction between the tires and the road, as well as internal friction in the engine and other components, converts some of the mechanical energy into heat energy which is dissipated into the environment. Also, the electrical energy used by the electrical systems is eventually dissipated as heat when the electrical components operate.

Answer:

For a car system, energy enters as chemical energy in gasoline, transforms into thermal, mechanical, and electrical energy, and leaves as heat in exhaust gases, heat from friction, and heat from electrical - component operation.
