Question

describing the flow of energy in heat engines
which series represents the flow of thermal energy in a heat engine?
fuel → air inside piston chamber → air outside piston chamber
fuel → air inside piston chamber → piston movement
fuel → piston movement
fuel → air outside piston chamber

Explanation:

In a heat engine, fuel is burned. The thermal energy is first transferred to the air inside the piston chamber (due to combustion). Then, this thermal energy is converted into mechanical energy (piston movement). The first option (Fuel → air inside piston chamber → air outside piston chamber) just shows heat transfer without[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]
