As the volume is decreased, the same number of molecules of air have a smaller space to move freely in. The number of collisions of molecules of air with the walls of the container per unit time increases. Since pressure is the force exerted over an area, the pressure increases.

∙ 15y agoif the volume is reduced the gas has less space to move around in so it will exert more pressure on the walls of its container. It is like squashing the same amount of gas into a smaller container, there will be more pressure

Does water temperature affect speed?
Yes, but the effect should be minimum. As water cools it becomes more dense, Meaning that there is more mass per volume. As a boat moves through a given volume it must displace some of the water. Since ( F = M * a ) the boat must exert a certain force to move an amount of water. If there is more mass in that certain volume the boat must exert more force, thereby slowing the boat.
What causes a gas to exert pressure when confined in a container?
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
When the temperature of a gas decreases at constant volume its pressure increases?
pressure. simple answer is pressure. what happens is that as the gas gets hotter they move move and want more volume, if you don't allow them that volume the pressure goes up. when you get a gas colder, the opposite happens and makes the pressure go down.
Which of the following would increase the pressure of a gas?
Lying on an air mattress
What happens to the pressure of a gas if the volume of a gas is tripled at a constant temperature?
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume
Which needles are made to exert more pressure?
Pressure exerted
Why does the heated air exert more than pressure than the unheated air?
It doesn't unless it is constrained in a constant volume container. When in a container, as the air is heated its molecules vibrate more and take up more volume - as the volume of the container is fixed then Charles's law applies and the pressure goes up.
What is the volume that you can fill by evaporating one ounce of helium liquid?
It will fill any container you evaporate it into, and still exert pressure on the inside of the container in its relentless quest for more volume. That's just what gases do.
Which will exert more pressure river water or same amount of sea water?
Salt water is denser, and therefore will exert more pressure (for two columns of the same height).
Will you exert more pressure when you stand on your toes or when you stand flatfooted?
on your toes
Will you exert more pressure when you stand on your toes or when you stand flat footed?
Total pressure is the same in either case, but on your toes, you exert more pounds per square inch, on fewer square inches.
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.
What happens to the volume of a gas inside a cylinder 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.
Why does water exert more pressure than air?
Water is more dense than air is.
Why does a pointed heal shoe exert less pressure?
Sorry - it exerts more pressure than a flt heel.
Does a gymnast exert more pressure on the floor when she does a handstand or when she does a split?
The gymnast exerts more pressure by doing the split because she has a bigger surface.
What change in volume would cause the pressure of an enclosed gas to be reduced toone quarter of its original value?
This is the reduction of volume to one-third.
