To increase the volume of a gas * reduce the pressure, or * increase the temperature, or * add more gas
The volume increase when the amount of gas increase.
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.
If possible, the gas will increase in volume. If it is unable to increase in volume for some reason, it will increase in pressure.
more gas If you increase the volume without adding more gas, the pressure decreases.
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
Decreasing the pressure applied to the gas (apex)
If the pressure on a gas is decreased, the volume of the gas will increase. This relationship is described by Boyle's Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. As pressure decreases, the gas particles have more space to move, causing an increase in volume.
Gas tends to take the shape of the volume it's in. If the volume is reduced, then the pressure of the gas will increase.
An increase of the temperature or a decrease of the pressure.
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.
if volume of a gas increases temperature also increases
To increase the volume of a gas, either the temperature must rise or the pressure must decrease, according to Boyle's Law and Charles's Law. This relationship is known as the ideal gas law, which states that the volume of a gas is directly proportional to its temperature and inversely proportional to its pressure.
