Greater pressure on a gas will compact the gas into a smaller volume. If the compressed gas is then warmed, it will try to expand, and the pressure the gas exerts on the container will increase. If the pressure becomes greater than the container can hold, the container will explode or split and the excess gas pressure released.

At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.

By increasing the volume of a gas, at the same temperature, the gas molecules are applying the same force over a larger area. Because pressure = force divided by area, the pressure decreases.

This is a consequence of Boyle-Mariotte law: pV=k. at constant temperature.

At a constant temperature what is the impact to volume if the pressure is increased?

Volume & pressure are inversely proportionate, if temperature stays constant volume would decrease at a factor proporionate to the increase in pressure.


What happens to a gas temperature at a given pressure?

In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.


When the temperature of of gas increases at constant pressure its?

As pressure increases, if temperature is constant, the gas will decrease in volume.


What happened to the pressure and temperature when you increased the volume of the gas?

Pressure and temperature will decrease


When the temperature of a gas increases at constant pressure it's?

As pressure increases, if temperature is constant, the gas will decrease in volume.


When the temperature is constant will the the volume of a gas decrease as the pressure decreases?

At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.


What will cause a decrease in a gas pressure in a closed container?

A loss of gas, or a decrease in temperature.


When the pressure of a gas increases at constant temperature its volume?

Temperature increases as pressure increases.


When the temperature of a gas is constant will the volume increase or decrease as the pressure decreases?

as the pressure decreases the volume of gas increases at constant temperature


As pressure increase what does volume do?

since PV=nRT and we assume that the number of moles and temperature remains constant, we can assume that PV=R as R the gas constant will not change, if pressure is increased, then volume must decrease to counteract the change in pressure


How can pressure be increased or decreased?

Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse


What happens to the pressure as the volume changes?

Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
