What are causes of the movement of the Earth?
the wind creates a force acting onto the air, which in then pushes the air to move in the direction of hte applied force the wind creates a force acting onto the air, which in then pushes the air to move in the direction of hte applied force
Does hot air have low pressure?
No
Why is it advisable not to increase the air pressure in a car tire to full limit when driving on hot day?
AnswerTire pressure is supposed to be measured while the tire is cold. Tire pressure is higher when the tire is hot; therefore, the pressure of a hot tire will drop below its limit when it cools down.
Why air blows from cold place to hot place?
Differences in air pressure.
Why does hot air exerts low pressure?
Because warm air is less dense than cold air.
Why flames of a fire rise even though gravity pull thing downwards?
Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.
What makes the hot air balloon go up and down?
The hot air from the fire pushes the balloon up, and putting out the fire makes it go down again :)
Why is air pressure at the top of a chimney less than air pressure at the bottom?
Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney

How is a Warm Front formed?
they are formed when hot air pushes against cold air
What is a hot air ballons air pressure?
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
how are hot air balloons different then planes in lift?
The hot air inside the balloon is less dense than the cold air outside, so the balloon floats on the denser air. But an airplane relies on a wing moving through the air to create lower pressure on the top of the wing, so that air below pushes the wing up. hot air balloons require no movement.
Does a hot air balloon use the pneumatic system or hydraulic system?
Neither. Pneumatic equipment uses air, under pressure, to convey mechanical energy from one place to the other. Hydraulic equipment uses water for the same reason. A hot-air balloon uses less dense hot air to fill it's balloon. Due to gravity the more dense cold air sinks down and pushes the hot air filled balloon up. The burner uses a mechanical arm with a spring (with a string and handle attached) to control the amount flame.
Is pressure hot air?
Air pressure is the weight of the atmosphere pressing down on the earth. Temperature raises and lowers the pressure by changing density of said air. For example check the air in your cars tires cold, then hot-with no other change besides temperature, you will get different readings-this is normal and the reason you are supposed to adjust when cold.
What make a hotair balloon go up?
Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!
What makes a hot air balloon works?
a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
