Will the efficiency of a car engine increase, decrease; or remain the same if the muffler is removed? If the car is driven on a very cold day? Defend your answers.
To explain: The efficiency of a car engine when muffler is removed and the car is driven on a very cold day.
Explanation of Solution
Introduction:
Efficiency is a term which is used to define the performance of the system. A system is called is more efficient when you receive maximum work and less waste.
When you remove the muffler from the engine of the car then the back pressure of the car will reduce and hence the car will give you maximum work. So, the efficiency of the car will increase. In the case of very cold day, the efficiency of the car will increase and the reason for this is the temperature difference between the surrounding and the hot reservoir.
Conclusion:
Hence, the efficiency of a car engine when muffler is removed will increase and in a very cold day the efficiency of car will also increase.
