An inventor states that the new engine
invented rejects 30% of the heat it absorbs from the reservoir, while the
temperature of the source and the sink are maintained at 500 K and 200 K
respectively. His engine is equivalent to ________.
एक आविष्कारक का कहना है कि आविष्कार किया गया नया इंजन जलाशय से अवशोषित गर्मी का 30% अस्वीकार कर देता है, जबकि स्रोत और सिंक का तापमान क्रमशः 500 K और 200 K पर बनाए रखा जाता है। उसका इंजन ________ के बराबर है।
Carnot engine
Joule engine
Impossible engine
Stirling engine
Impossible engine
Given:
Therefore,
this engine is not possible.
..Method 2..
Thus it is not possible for an engine to have higher efficiency than
Carnot engine, so it is impossible.
Hence,
the correct option is (C).
