No, air conditioners do not take in outside air to cool a room. They recirculate and cool the air that is already inside the room.
Ductless air conditioners are those that fit into a window. They take in air and cool it, then a fan forces the cool air into a room. The average cost for a small ductless air conditioner is around $125.
Air conditioners take in air from outside through a vent or intake system, which draws in the warm air from the surrounding environment.
You can, in fact only use the exhaust hose and let the unit draw air from the inside, but you would lose the efficiency benefit gained from buying a dual hose unit. The air it draws in is air that you have already paid to cool. It would draw this air inside the unit to cool the compressor and the condenser coils. Then it would exhaust that air outside. With two hoses, it is using the warm, outside air to cool the air conditioner coils, so you are not paying to cool the components, only the air in your room. I strongly recommend using both hoses.
Air conditioners are typically installed on the top to take advantage of the principle that cool air sinks and warm air rises. Placing the AC unit high up allows for better distribution of cool air throughout the room. Room heaters, on the other hand, are placed on the floor to provide warmth at ground level where occupants are more likely to feel the heat.
Automotive air conditioners are used to cool a very small enclosed area and would most likely not be able to keep an entire room cool unless it is the size of the automobile that it was removed from. Even if you were able to hook it up, the cost of the electric or fuel that it would take to run the unit would cost more than if you were to purchase a small window unit and put that in your window.

because the yeast reacts to heat.
Not all AC's are in or near the ceiling. Many go in windows and there are a number of portable units. But the principle is, heat rises, cool air falls. So the higher the cool air starts to fall is, the more warm air it cools on the way down.

The time it takes for boiled water to cool down depends on factors like the volume of water, the temperature of the room, and the material of the container. Generally, it can take anywhere from 30 minutes to a few hours for boiled water to cool down to room temperature.
