It depends on the pitch of the blades.

Why is it best to place a room heater on the floor but air conditioner near the ceiling?
Because according to physics heat goes upward from downward and cool air goes upward to downward so it is best to place heater on the floor but air conditioner near the ceiling
How does convection happen in a room?
Warm air flows toward the ceiling and cool toward the floor. (expansion with heat results in lower density)
Why it is more effective for heaters to be place close to the floor and coolers to be place closer to the ceiling?
hot air raises, cool air will drop. This helps set up convection currents to disperse the heat/cool throughout the room.
How do the blades of a ceiling fan turn for cool air?
Clockwise
Why are air conditioners placed high on walls and not on the ground?
Because the cool air from the air conditioner is denser than the warm air in the room and sinks. Placed high up the cool air will have time to get further from the air conditioner before it settles to the floor, allowing it to cool more of the room. Placed on the floor the cool air will mostly pool around the air conditioner and very little of the room will be cooled. Some air conditioner are actually placed relatively low in a room, but they have fans and baffles that blow the cold air upwards to the ceiling resulting in the same effect as placing the air conditioner high (maybe even better as the fan blows the cool air not only up to the ceiling but across it, possibly covering a larger volume of the room than cool air falling passively from an air conditioner placed high but without fans).
Why is the air temperature near the ceiling of a room tends to be warmer than near th floor?
The hot air is lighter than the cool air so it floats to the ceiling.:)
What would happen if you tried to heat a room with a radiator that was positioned at the top of the wall?
The ceiling will be very warm, while the floor will be cool.

Which direction is a ceiling fan supposed to go in the summer clockwise or counter clockwise?
Depends on how the blades are angled. In winter, you want it to blow the warm air off the ceiling, to the floor. In summer, you want it to pull the cool air upwards.
Air deflector for ceiling air conditioner vents?
Cool air falls toward the floor. Deflectors shouldn't be necessary unless the vent is behind a curtain or something, or if you want to deflect the cool air toward your easy chair.

hot air raises, cool air will drop. This helps set up convection currents to disperse the heat/cool throughout the room.
How is the revolution and rotation on Jupiter?
its cool
can a ceiling fan cool an entire house?
A single ceiling fan cannot cool an entire large home. However there are whole home fans which can achieve this.
Why the air temperature near the ceiling of the room tends to be warmer than near the floor?
Because warm air rises over cool air. Warm air is less dense than cool air, and it's lifted by buoyancy and floats on the more dense cool air.
How do you determine what size ceiling fan for a room 14'x15'?
A 36" fan should be adequate. Mount it at least a foot from the ceiling (18" is better) and run it reversed, to draw the cool air up from the floor and spread it around the room. That will also reduce drafts and dust.
