## Related Questions   Assuming temperature and moles of gas remains the same, then decreasing the volume of the gas will increase the pressure. Decreasing the volume enough will result in non ideal behavior. pressure will not affect the volume of solids to the gases:The pressure increases, the gas volume will reduce; The pressure reduces , the gas volume will increase decreasing the volume available for the gas or increasing its temperature  As indicated by Charles's Law, at constant pressure, the volume decreases when the temperature decreases. This is due to slowed collisions between molecules. Reducing the volume will increase the pressure of the gas. Increasing the pressure the volume of a gas decrease.   As the pressure of a gas increases, the volume will decrease and vice versa. If the temperature of the gas is decreasing, then in order to maintain constant pressure, you would have to compress it in volume. The mass of the gass, the volume of the container holding the gas, and the temperature of the gass. If you have a container of gas, the greater the mass of the gas, the more molecules there are in the container, and this leads to greater pressure. If you have a fixed mass of gas, changing the volume of the container holding the gas will cause the pressure to change. Increasing the volume of the container decreases the pressure. Decreasing the volume of the container increases the pressure. If you increase the temperature of a gas without changing its mass or volume, pressure increases. Decreasing the pipe diameter for the same flow volume increases the flow rate and therefore reduces the pressure of the gas by Bernoulli's principle. At constant temperature p.V=constant, so pressure INcreases when decreasing the volume. There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure. Yes. However the volume of a gas must be constant or decreasing. If the volume is increasing then the pressure may not be increasing. For apex the answer if False. If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon. If the volume is fixed, then increasing the temperature will increase the pressure, and decreasing the temperature will decrease the pressure. This would be the case for a gas in a closed solid container, like a canister or sealed metal box. Increasing pressure will cause the gas to contract (reducing the volume), and decreasing the pressure will cause the gas to expand (increasing the volume). Again, this is if the volume is not fixed. If the volume is fixed, then increasing the pressure will increase the temperature, and decreasing the pressure will decrease the temperature. These concepts are all determined by something called the Ideal Gas Law. To find out more about how this works, see the Related Questions links below this answer. Gases can also be changed to a liquid or solid if the temperature is too low or the pressure is too high. As an example steam changes to a liquid when it touches a cold object, and nitrogen gas can be converted to liquid nitrogen by compressing it to very high pressures. At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.  If pressure is kept constant, the volume will decrease.If volume is kept constant, the pressure will decrease.  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. Decreasing the pressure or increasing the temperature would increase the volume of ideal gas in a closed container with variable volume.V = nRT / P
