Cold air will sink and hot air will rise. So ACs are placed up higher.
A step-down transformer reduces the voltage from a higher level to a lower level, while a step-up transformer increases the voltage from a lower level to a higher level.
To effectively siphon water from a lower level to a higher level, you can use a tube or hose to create a vacuum that pulls the water up. Start by filling the tube with water and then sealing one end with your finger. Place the sealed end in the lower level of water and the other end in the higher level. Release your finger from the sealed end to let gravity pull the water up the tube. Make sure the higher end of the tube is higher than the lower end to create the necessary pressure difference for the siphoning to work.
Pitch level refers to how high or low a sound is perceived by our ears. It is determined by the frequency of the sound waves, with higher frequencies corresponding to higher pitch levels and lower frequencies to lower pitch levels.
Yes, pressure is lower in the mountains compared to sea level.
Water can be transported from a lower level to a higher level through mechanisms such as pumps or hydraulic systems. These systems use force to overcome gravity and move water against it. The principle that water seeks its own level refers to its natural tendency to find equilibrium when allowed to flow freely.
air-conditions are usually placed at a higher level rather than at a lower level.
hot air rises so the air con will cool down the air above so air cons will be placed at a higher level
Hot air rises but not cold air.
Two reasons. One, cold air doesn't rise - it sinks. Two, hot air rises. One of the functions of an air conditioner is to remove humidity from the area being cooled - thus, the hot air will rise into the AC intake.
he said that things can only fall from a higher level to a lower level not from a lower level to higher level
Unlike warm air, cold air does not rise - it falls to the ground. Thus, it's more ideal for an AC system to be placed high rather than low.
Because hot air rises.
