A salesperson tries to sell you a "new and improved" air conditioner that does not need a window opening. The unit just sits in the corner of the room and keeps it cool.

Use the second law of thermodynamics to convince the salesperson that this will not work.

Answer :

Final answer:

The second law of thermodynamics states that heat flows from a region of higher temperature to a region of lower temperature. Without a window opening, heat cannot be efficiently removed from the room, and the air conditioner will not work.

Explanation:

The second law of thermodynamics states that heat will always flow from a region of higher temperature to a region of lower temperature, and it is not possible to transfer heat from a cooler region to a hotter region without the input of external work. In the case of an air conditioner, heat is removed from the room and expelled outside through a window opening. Without a window opening, there would be no way for the heat to be efficiently removed, and the room would not be cooled. Therefore, the salesperson's claim that a new and improved air conditioner does not need a window opening is not consistent with the principles of thermodynamics.
