In a heat engine, if the input heat is 500 J and the work done is 300 J, what is the efficiency? (2023) 2023

Step 1: Identify the input heat, which is given as 500 J.
Step 2: Identify the work done by the engine, which is given as 300 J.
Step 3: Use the formula for efficiency, which is Efficiency (η) = Work done / Input heat.
Step 4: Substitute the values into the formula: η = 300 J / 500 J.
Step 5: Calculate the result: 300 J divided by 500 J equals 0.6.
Step 6: Convert the decimal to a percentage by multiplying by 100: 0.6 * 100 = 60%.
Step 7: State the final answer: The efficiency of the heat engine is 60%.
