The next time the mechanic works with an overheated engine, she wants the engine to cool off quickly. What should she do to maximize the rate of thermal energy transfer out of the engine?
leave the hood of the car open
leave the hood of the car closed

To maximize the rate of thermal energy transfer out of the overheated engine, the mechanic should **leave the hood of the car open**.
In the scenario presented, the engine in the car with the open hood cooled down to a final temperature of 86°C, while the engine in the car with the closed hood reached a final temperature of 95°C.
This indicates that leaving the hood open allows for better air circulation around the engine, which promotes more efficient heat dissipation. Thus, keeping the hood open will help the engine cool off more quickly.
