In a Carnot engine, the efficiency depends on which of the following? (2023)
Step 1: Understand what a Carnot engine is. It is a theoretical engine that operates between two temperature reservoirs: a hot reservoir and a cold reservoir.
Step 2: Identify the two temperatures involved: T_h (temperature of the hot reservoir) and T_c (temperature of the cold reservoir).
Step 3: Learn the formula for the efficiency (η) of a Carnot engine: η = 1 - (T_c / T_h).
Step 4: Realize that the efficiency depends on the ratio of the cold temperature to the hot temperature.
Step 5: Conclude that to increase efficiency, you need a higher T_h and a lower T_c.
