If the temperature of the cold reservoir in a Carnot engine is increased while keeping the hot reservoir temperature constant, what happens to the engine’s efficiency?
The efficiency increases as the cycle becomes more reversible
The efficiency decreases because the temperature ratio between reservoirs is reduced
The efficiency increases due to more heat being absorbed
The efficiency remains the same as long as the working substance is unchanged
The efficiency decreases because the temperature ratio between reservoirs is reduced
