Answer is option b (increases) Carnot engine is the hypothetical heat engine designed based on carnot cycle in which heat delivered to the system is used to get mechanical work. We know that ; efficiency of a carnot engine is given by; η=1−T1/T2 Where,T1 is the temperature of source and T2 is the temperature of sink. So,if we increase the temperature of the source,the efficiency of the carnot engine also increases. |
If the temperature of the source is increased, the efficiency of the Carnot engine Select one:...
