A Camot engine with efficiency 50% takes heat
from a source at 600 K. In order to increase the
efficiency to 70%, keeping the temperature of sink
same, the new temperature of the source will be:
from a source at 600 K. In order to increase the
efficiency to 70%, keeping the temperature of sink
same, the new temperature of the source will be:
View answer and explanation
Correct option: D
1000 K
Option D (1000 K) is correct because it is calculated by first finding the temperature of the sink using the initial efficiency and source temperature, and then using the new efficiency and the same sink temperature to find the new source temperature.
