Solve the all parts of given question:
Question: In a car engine, gasoline is ignited by a spark plug to generate an explosion in a cylinder. Each explosion transfers 700 J of energy form the burning fuel to the gas cylinder. During the expansion (and later the contraction) of gas, the gas does a net 200 J of mechanical work on the environment (on a piston that pushes outward and helps propel the car).
Part A: How much energy is transferred through heating to the car's cooling system during this cycle?
Part B: What is the efficiency of the engine?
I need help to find how much energy is transferred through heating to the car's cooling system during this cycle.
