heat causes gases to expand
It would increase.
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.
no the presure would become greater unless the contianer became larger the volume would stay the same
If the pressure on a gas increases, its volume would generally decrease, provided that the temperature remains constant. This relationship is described by Boyle's Law, which states that pressure and volume are inversely proportional when temperature is held constant.
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.
heat causes gases to expand
If possible, the gas will increase in volume. If it is unable to increase in volume for some reason, it will increase in 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.
more gas If you increase the volume without adding more gas, the pressure decreases.
If the volume of the tank was effectivelly constant, and the tank was sealed to prevent gas escaping, the pressure of the gas would increase.
An increase in temperature or a decrease in volume would call the pressure to increase. Apex- increasing the number of gas particles
