Lying on an air mattress
You don't say by how much, so the only answer is that a decrease of pressure causes an increase in volume
A decrease in pressure would result in the increase in the volume of a gas provided that the temperature is constant.
Options:
-- Force more gas into the same container.
-- Force the same amount of gas into a smaller container.
-- Heat the gas.
- decrease of the volume
- increase of the temperature
increasing the number of gas particles - apex
The frequency of collisions is reduced.
Decreasing the pressure applied to the gas (apex)
it would change the pressure exerted by the gas in the container.
An increase in temperature or a decrease in volume would call the pressure to increase. Apex- increasing the number of gas particles
The pressure would increase.
According to the combined gas law, volume and pressure are indirectly related. Therefore, if the pressure of a gas increases, the volume will decrease.
Decreasing the pressure applied to the gas (apex)
Any of the following: increasing the amount of gas; increasing the temperature; reducing the volume.
decreasing the volume available for the gas or increasing its temperature
It would increase.
it would change the pressure exerted by the gas in the container.
The temperature
An increase in temperature or a decrease in volume would call the pressure to increase. Apex- increasing the number of gas particles
The pressure would increase.
Both compressing and heating a gas will increase its pressure.
If you increase the volume of the container, and not the gas itself, then the pressure decreases. If you increase the volume of the gas, and not the container, then the pressure increases.
According to the combined gas law, volume and pressure are indirectly related. Therefore, if the pressure of a gas increases, the volume will decrease.
As indicated by the Ideal Gas Laws, increasing temperature will tend to increase both volume and pressure. Of course, volume can't always increase, that depends upon the flexibility or inflexibility of the container that the gas is in, and if the volume does increase that will counteract the increase in pressure that would otherwise have happened. Temperature, pressure, and volume are all interconnected in a gas.
