Where do high pressure areas occur?
High pressure areas typically occur in regions where air descends towards the surface, leading to more air molecules being compressed in a given space. This results in greater atmospheric pressure at the surface, creating a high pressure system. High pressure systems are commonly associated with calm, clear weather conditions.
What type of pressure is created when hot air rises?
Hot air expands, and if in an enclosed space, will cause high pressure. If not enclosed, the hot air will "spread out". As a result, you would have less hot air in a given space than cold air filling an identical space. It is that question of density which makes hot air rise.
Why is the air thinner as you increase your altitude?
Air is compressed (squeezed) by the air above it (due to gravity), the higher you go, the less air there is above you.
If chlorine gas is compressed does its density increase?
Yes It does increase. http://webbook.nist.gov/chemistry/fluid/ While this website doesn't include chlorine, any gas that is compressed will increase in density. Different gasses all have different compression-density relationships, but all gasses that are compressed will increase in density.
Why does the air put pressure on people?
Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smallervolume.When it's compressed, air is said to be "under high pressure". Air at sea level is what we're used to, in fact, we're so used to it that we forget we're actually feeling air pressure all the time!Weather forecasters measure air pressure with abarometer. Barometers are used to measure the current air pressure at a particular location in "inches of mercury" or in "millibars" (mb). A measurement of 29.92 inches of mercury is equivalent to 1013.25 millibars.How much pressure are you under? Earth's atmosphere is pressing against each square inch of you with a force of 1 kilogram per square centimeter (14.7 pounds per square inch). The force on 1,000 square centimeters (a little larger than a square foot) is about a ton!Why doesn't all that pressure squash me? Remember that you have air insideyour body too, that air balances out the pressure outside so you stay nice and firm and not squishy.
What does the air pressure do when a sealed bag is compressed and more space is available in the bag?
When a sealed bag is compressed and more space is available in the bag, the air pressure inside the bag decreases. This is because the air molecules are now occupying a larger volume, leading to a lower pressure.
When a sealed bag is compressed less space is available in the bag and the air pressure?
increases. This increase in air pressure can cause the bag to expand outward, in an attempt to reach equilibrium with the surrounding pressure.
What happens to the pressure of fluid that is compressed in a confined space?
When a fluid is compressed in a confined space, the pressure of the fluid increases. This occurs because the molecules of the fluid are being pushed closer together, leading to a higher density and thus an increase in pressure.
Can gas particules cannot be compressed into smaller spaces?
Gas particles can be compressed into smaller spaces because they have a lot of empty space between them. When gas particles are compressed, their volume decreases due to the reduction in this empty space, resulting in an increase in pressure.
How can gas be compressed effectively?
Gas can be compressed effectively by reducing its volume while increasing the pressure applied to it. This can be achieved by using a compressor, which forces the gas into a smaller space, causing its molecules to come closer together and increasing its pressure.
Can the particles in gas be compressed into smaller volume?
Yes, particles in a gas can be compressed into a smaller volume by reducing the space between them. This will increase the pressure of the gas as the particles are forced closer together.
What happened to the pressure when air was compressed?
When air is compressed at the same temperate and volume space, pressure will increase in accordance with Boyle's Law which states: PV/T (initial) = PV/T (final) where P is pressure, V is volume and T is temperature.
Why does the volume of a gas decrease when pressure increases?
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
Why does fuels burn faster in compressed air?
fuels combust with greater efficiency in a compressed environment due to the higher content of oxygen molecules within the defined space, under pressure you will also get an explosion due to the sudden increase in pressure within the already high pressure environment
How is pressure affected when a gas is compressed?
When a gas is compressed, its volume decreases while the number of gas molecules remains the same. This leads to the gas particles being more concentrated in a smaller space, resulting in an increase in pressure according to the ideal gas law, which states that pressure is inversely proportional to volume.
Do compressed oxygen in a pressurized tank show a decrease in fluid pressure?
Yes, compressed oxygen in a pressurized tank will show a decrease in pressure as the gas is released from the tank. This is due to the gas expanding to fill the space as it exits the tank, resulting in a decrease in pressure within the tank itself.
What do you say when air is pushed into a smaller space?
Compression occurs when air is pushed into a smaller space, increasing its pressure and temperature as the molecules are forced closer together.
