How does density change as air pressure increases?
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
If your volume has changed how will your density change?
It will be reduced.
What can you say about the pressure at a point as the direction of the funnel changes?
The pressure will change. How it will change will depend on where, within the funnel, the point is.
How can pressure change the density of solids liquids and gases?
Pressure can change the volume of all three (to varying degrees) and density = mass (which doesn't change) divided by volume.
What are the two ways pressure can change?
You can change it's area or its temperature.
What happened to volume of a gas inside a cylinder if the temperature does not change but the pressure is reduced?
Assuming your cylinder is fixed and has something like a piston allowing for potential movement, the volume will remain the same. The gas will become less densed, as with pressure its more dense.

How do you calculate volume after some pressure is released from cylinder?
The volume should not change if the cylinder is rigid.
How does density change as air pressure increases?
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
2 ways how the risk of developing a pressure sore can be reduced?
It can be reduced by regular position change and eating a healthy diet.
A metal cylinder contains 1 mol of nitrogen gas what will happen to the pressure if another mole of gas is added to the cylinder but the temperature and volume do not change?
The pressure would double in size.
What will happen if you change the pressure of a rugby ball?
If its reduced the ball absorbs the pressure of a kick making the ball fly much less if at all, the bounce in the ball is reduced and the passing is like throwing a wet sponge. - If over pressurised the ball continues to bounce in the normal way but the shape will change causing the aerodynamics to change
What will happen when we start putting pressure and compress a gas enclosed in a cylinder and do you think increase and decrease in pressure can change the state of matter?
At high pressure the gas become a liquid.
Why would a country change its policies as a result of a boycott?
The country would face economic pressure because of reduced trade or growth.
How does the volume of an cylinder change if the radius is reduced to of its original size and the height is quadrilpled?
This could have been an intriguing little exercise if you hadn't left the fraction out of the question. (If the fraction was supposed to be 1/2 then the answer is "No change".)
Do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
Percentage of oxygen at 10000 feet level?
The percentage of oxygen in the atmosphere does not change with altitude, so it is about 21% at 10 000 feet. What does change is the pressure. This declines with altitude. At sea level the air pressure is about 101 kPa (kilopascals). Oxygen accounts for 21% of this so the oxygen pressure is 19.6 kPa. This means that there are less oxygen molecules in the same volume of air at higher altitudes. At 10000 feet the oxygen pressure drops to 7.2 kPa, which is roughly one third of the pressure at sea level. For an online calculator of oxygen levels at different altitudes see: http://www.altitude.org/calculators/oxygencalculator/oxygencalculator.htm This site also lets you convert between kilopascals and mm Hg.
