Their inverse relationship.
volume increases ,pressure increases
In the relationship between volume and pressure when volume increases pressure decreases and when volume decreases pressure increases.
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
For a gas, pressure and volume are inversely related. If pressure decreases, volume will increase.
Pressure, volume, temperature & the amount of gas.
Compression reduces the volume without changing the amount of content it has. Pressure is inversely affected by volume. When volume increases, pressure decreases. Likewise, when volume decreases, pressure increases.
There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
For a given mass at constant temperature, the pressure time tghe volume is a constant. pV=C
"When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases." More precisely, pressure is inversely proportional to volume.
It would be half of the original volume. As you reduce the volume the pressure would increase and at half the original volume the pressure would be doubled.
Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
Since pressure is inversely proportional to volume(according to Boyle's law), if volume decreases, pressure will increase and vice versa i.e. volume increases pressure decreases!
