Q
Q: In a heat engine, if the work done is 200 J and the heat absorbed is 500 J, what is the efficiency?
Solution:
Efficiency = (Work done / Heat absorbed) * 100 = (200 J / 500 J) * 100 = 40%.
Steps: 7
Show Steps
Step 1: Identify the work done by the heat engine, which is given as 200 J.
Step 2: Identify the heat absorbed by the heat engine, which is given as 500 J.
Step 3: Use the efficiency formula: Efficiency = (Work done / Heat absorbed) * 100.
Step 4: Substitute the values into the formula: Efficiency = (200 J / 500 J) * 100.
Step 5: Calculate the fraction: 200 J / 500 J = 0.4.
Step 6: Multiply by 100 to convert to percentage: 0.4 * 100 = 40%.
Step 7: Conclude that the efficiency of the heat engine is 40%.
