Take a tin can with a lid. Fill it approximately with half of water. Heat the can on a candle flame till the water boils. Let the water boil for a few minutes. Blow out the candle. Immediately put the lid tightly on the can. Be careful in handling the hot can. Put the can carefully in a shallow metallic vessel or a washbasin. Pour fresh water over the can.
THE CAN GETS DISTORTED DUE TO THE AIR PRESSURE EXERTED.
If you can't get a tin can, take a soft plastic bottle. Fill it with hot water. Empty the bottle and immediately cap it tightly. Place the bottle under running water.
Here are 2 examples: - hot airballoon - hot air rising, and cold air falling.
Some examples are, hot air ballons, ships, bouys, actually just about anything that floats in air or water :p
In a Cartesian diver, the air behaves as it does due to the principles of buoyancy and pressure. When the container is squeezed, the water pressure increases, compressing the air inside the diver. This increased pressure reduces the volume of air, making the diver denser than the surrounding water, causing it to sink. Releasing the pressure allows the air to expand, decreasing the diver's density, and making it buoyant again, allowing it to rise.
Because it doesn't say neither the temperature, the pressure or the humidity of the air. You need to know both the temperature, the pressure and the humidity of the air to say anything about the mass of one cubic meter of air.
Running water moves the air next to it. Moving air has less pressure than air that is still. This is the Bernoulli principle, and helps airplanes to fly. With less pressure on one side from moving air, and more pressure on the other side from still air, the ping-pong ball moves towards the water.
When air exerts a force, it is called air pressure. Air pressure is the force exerted by the weight of air above a given point.
weight
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
devin in it
Exerting pressure is the act of applying force or weight on an object or surface. This pressure can cause a change in the state or shape of the object. Examples of exerting pressure include pushing, squeezing, or compressing an object.
One experiment that proves that air exerts pressure is the collapsing can experiment. In this experiment, a small amount of water is boiled in a can, and the can is then sealed. As the steam cools and condenses, it creates a vacuum inside the can, causing the outside air pressure to crush the can. This demonstration shows that air exerts pressure.
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
1 atm
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.
air molecules in cold air exert more pressure because they are closer together and collide more often
Air pressure is generally lower in warm areas because warm air is less dense and therefore exerts less pressure on its surroundings. Cool air is denser and exerts more pressure, so areas with cooler temperatures typically have higher air pressure.
The force that air exerts on your body is called air pressure. This force is a result of the weight of the air above you pressing down on your body.
