Question

Can a car not engine work if its sink and source are interchanged

Answer 1

Answer:

Carnot engine cannot work if source and sink are interchanged. This is because isothermal expansion should take place first. If the cylinder is placed on the sink first, then isothermal compression takes place, which is literally not possible.

Answer 2

Answer:

No the car not engine cannot work.

Explanation:

It is impossible for a carnot engine to work when the source and sink are interchanged.

Since, we know for the carnot engine to work their must first isothermal expansion take place first. Now if the source and sink gets interchanged then after the body placed on the sink first, then at first isothermal compression takes place, which is absolutely impossible.
