Which of the following is a box-like device that changes air in the room into air with more oxygen?

1. Air conditioner
2. Air purifier
3. Fan
4. Humidifier

Answer :

Final answer:

None of the listed options (air conditioner, air purifier, fan, humidifier) is designed to increase the oxygen content in the air. An air conditioner cools the air by removing heat, not by adding oxygen. For increased oxygen levels, specialized oxygenation devices would be needed. So, the correct option is 'None of these'.

Explanation:

The student's question pertains to a device that converts air in a room into air with more oxygen. Among the listed devices, none are designed specifically to increase oxygen levels in the room; an air conditioner cools the air by removing heat, an air purifier cleans the air by removing contaminants, a fan circulates air but does not change its oxygen content, and a humidifier adds moisture to the air.

An air conditioner operates using either a vapor compression, vapor absorption, or open-loop evaporative system to remove heat from the surroundings by the evaporation of a fluid, which is a phase-change process. It is primarily used to keep indoor environments cool and comfortable by removing heat from the indoor air and releasing it outside. The process of air conditioning does not increase the concentration of oxygen; instead, it adjusts the temperature and, at times, the humidity levels in an enclosed space. For clean and oxygen-rich air, specialized oxygenation systems or devices that emit oxygen, like those used in medical settings, would be required. They are not typically found in homes or standard consumer appliances.
