An inventor says, he has invented an
engine which will reject 20% of heat absorbed from the source and the engine
operates between 2000 K and 500 K. What kind of engine it is?
एक आविष्कारक का कहना है, उसने एक ऐसे इंजन का आविष्कार किया है जो स्रोत से अवशोषित गर्मी का 20% अस्वीकार कर देगा और इंजन 2000 K और 500 K के बीच संचालित होता है। यह किस प्रकार का इंजन है?
Carnot engine
Diesel engine
Dual engine
Impossible engine
Impossible engine
Using Clauses inequality:
Therefore,
it does not satisfies Claudius inequality.
..Method 2..
Thus, no engine working under same
temperature condition has higher efficiency than the Carnot engine. Therefore,
the engine is impossible.
Hence,
the correct option is (D).
